Controversial S#!T

Justin Trudeau's not living in a love story with some Canadian citizens right now ... 'cause while he busted a few moves at Taylor Swift's Toronto concert, Montreal experienced some pretty scary rioting.

Here's the deal ... just as JT was singing his heart out and dancing with a few people in Rogers Centre Friday night, pro-Palestine protests evolved into full-scale rioting as people in masks bashed windows with hammers and lit cars on fire.

The videos are harrowing ... and, many people are calling out Trudeau for taking the night off while Montreal appeared overrun with protesters.

Patrick Mahomes got a big penalty for a game, but not for a play ... as far as the refs were concerned, it was way more ominous.

The Kansas City Chiefs QB was fined just over $14,000 for what officials called a "violent gesture" toward the end of the game against Buffalo last Sunday.

Mahomes had just thrown a touchdown pass and decided to celebrate by using his fingers to mimic the firing of a gun.

Influencer Julian Barboza has been arrested following an altercation with his girlfriend, TMZ has learned.

Law enforcement sources tell TMZ the Beverly Hills Police Department was called to a party around 2:00 AM earlier this month ... where Julian’s girlfriend met them outside and detailed what went down.

Cops say Julian and his girlfriend got into a verbal argument, and he asked her to leave the party. However, we're told things escalated when the GF started recording the argument on her phone, prompting Julian to allegedly grab it from her and throw it on the floor.

Diddy's house is underwhelming when you walk in and defintely not worth $60 million ... this according to the investor who says he's offering half the asking price.

We caught up with Bo Belmont -- founder and owner of real estate company Belwood Investments -- out in Los Angeles Friday ... and, we had to ask him about putting in a $30 million offer for the rapper's Holmby Hills mansion.

First off, Belmont says this is a real offer ... telling us his company has emailed the listing agent for the property -- though they haven't heard back yet.

Dana Carvey's "Saturday Night Live" impression of Elon Musk upset the tech mogul ... and, even the comedian has to admit he doesn't really sounds like the guy.

Here's the deal ... Dana and David Spade were chatting about an old 'SNL' memory on a recent episode of their "Superfly" podcast -- with Dana telling a story about how a hair dryer basically turned into a blowtorch and burned his locks.

Spade cracks a joke about Elon thinking a blow dryer turned flamethrower is a good idea ... and, DC does his impression -- immediately followed by saying he "can't do Elon Musk very well, but I can do something that sounds not like anything."

The autograph hound who went nuclear on Jason Kelce outside "Jimmy Kimmel Live!" last night was living up to a reputation he's earned in Hollywood ... as a guy who likes to explode on celebs -- at least according to cops.

Law enforcement and 'Kimmel' security sources tell TMZ ... the guy who's seen on video calling Jason a "p***y" is a regular at the studio and Hollywood premieres, and always shows up when celebs get their stars on the Hollywood Walk of Fame.

We're told the autograph-seeker gets famous people's signatures all the time ... and once in a while, he pops off like he did in our video after Jason's Thursday appearance on 'Kimmel.'

John Stamos is firing back at critics who slammed him for wearing a bald cap while shaving his buddy Dave Coulier’s head as DC battles an aggressive form of cancer.

We caught up with John at LAX, and he’s not having it, telling us he’s actually embarrassed for the haters ... saying they’re wasting time making hate videos and comments when they could be using that energy to call their doctors and get checked out.

Check out the full video 'cause John’s shock is crystal clear -- especially as he gets real to us about how it's hurt him, explaining he was just trying to cheer up a friend when Coulier asked him over to shave his head.

Kacey Musgraves is going above and beyond to make amends with her hometown ... dropping thousands of dollars on a scholarship fund after putting her foot in her mouth.

TMZ has confirmed ... the country singer made a donation to a scholarship fund in Golden, Texas after previously claiming her hometown was not something to "cheer for" during a concert in Canada.

The singer shelled out a whopping $10K to the scholarship fund and penned a lengthy apology note on her Instagram Stories ... where she called the dig "a sarcastic, completely unserious joke."

LaMelo Ball is adamant he's not a bigot ... telling reporters Sunday that even though he used some anti-gay language earlier in the weekend, he has "love for everybody."

Ball was fined by the NBA just prior to his Sunday evening meeting with the media ... after league officials deemed the "no homo" comment he made in a postgame interview on Saturday "offensive and derogatory."

Ball told journalists following the Hornets' 128-114 loss to the Cavaliers that he "really didn't mean anything" by the remark ... and he doesn't "want to offend anybody."

Josh Brolin's telling all about his relationship with his mother in his new memoir ... touching on her drinking -- and, mentioning one scary trick his mother used to pull on him.

The actor sat down for an interview with The Times -- published Saturday -- to talk about his book, "From Under the Truck," a reference to a night of heavy drinking that ended with his mother's boyfriend literally passed out underneath a vehicle.

In the article, the interviewier mentions a story Brolin relays in the book ... about how his mother Jane -- a wildlife conservationist -- would often yell at "Sic 'em" to any wild animals like courgars, coyotes, bobcats and the like nearby which would then usually take off after Josh and his brother Jess.

Chrishell Stause is back on "Selling Sunset" ... this despite saying she'd only film with Nicole Young again if the show forked over some serious dough.

Sources connected to the show tell TMZ ... Chrishell and Nicole are currently filming season 9 of the hit house-selling show after Chrishell said publicly in September that she wouldn't come back to the show if Nicole returned.

She later amended her statement ... saying in an interview she'd come back if the production team would "add a zero" to her check -- but, still it seemed unlikely the two would share the screen again.

Kate Upton is out to her millions of Instagram followers about a very troubling scenario ... and it's safe to say she has people worried.

The supermodel recently posted on her Instagram stories a cryptic and disturbing question ... addressing her query to "lawyers/judges/advocates/law enforcement/parents" before going into detail.

Her message continued ... "A Dad, recently out of rehab, is traveling alone with his 10-year-old daughter. He gets drunk and high on pills, says he has a gun on him and threatens to SHOOT the taxi driver if he does NOT drop them of on the highway at midnight to walk home."

She added that the taxi driver in the scenario refused ... and "would rather be shot than drop the little girl off on the highway" ... with the conclusion, "Is this an emergency? A Crime? Would you be scared for your child?"

Fans were baffled by the question ... and had no idea how to take what appeared to be a serious ask from "Sweet Dreams" star.

Kate and her MLB star husband Justin Verlander share a 6-year-old daughter named Genevive ... the couple married in November 2017, but there's obviously no way of knowing if the message is at all related to someone in her inner circle.

A 145-year-old bakery in Staten Island wants an apology from Whoopi Goldberg ... because they say her claim they denied her order over her left-leaning politics couldn't be further from the truth.

Here's the deal ... Whoopi had Charlotte Russe -- the dessert, not the store -- on "The View" this week as a sweet treat for her 69th birthday, and during the segment, she said she wouldn't name the bakery that made the cakes, because she felt they initially refused to make them for her ... because they didn't like her politics.

Whoopi told the audience the bakery blamed their ovens when she tried and failed to pre-order some Charlotte Russe cakes ... but she said someone from the show was able to go over to the bakery and pick up the grub on the morning of her birthday, leading her to suspect her support for Kamala Harris was the real culprit.

Megyn Kelly didn’t hold back ... calling actress Rachel Zegler "a pig" after the "Snow White" star made a fiery Instagram post wishing Trump supporters would "never know peace" post-election.

Rachel's since apologized following the backlash ... but the conservative commentator ripped into her on SiriusXM Thursday, while calling for Disney to redo their entire live-action remake of the classic cartoon, which has already been filmed with Zegler in the lead role.

Megyn fumed, "Picture this, a Broadway actress who said, 'F Biden supporters, may Biden and Kamala never know peace.' That person would be fired so fast it would make your head spin."

Pharrell Williams had a unique approach to a swarm of animal-rights protesters -- he went full hug mode to keep the peace ... and spoiler: it didn’t exactly work.

The singer and Louis Vuitton men’s creative director was heatedly heckled outside GQ’s Men of the Year Party at the Chateau Marmont Thursday night, with one protester yelling, "What type of person still uses fur?” Pharrell, ever cool, shot back with, “I don’t. God bless you."

The drama unfolds in the video -- the same protester held up a sign to show Pharrell the impact of his apparent fur use on animals, but the singer tried to go in for a hug -- only to have his efforts totally rejected.
