This Morning's Cat Deeley didn't prove very popular with ITV fans after she revealed most of the details about a TV programme fans were hoping to watch.
On Wednesday's programme, Cat was joined on the show by Dermot O'Leary, who was stepping in for her usual co-star Ben Shephard this week. They welcomed Billy and Susan Mail, the stars of a new Disney+ series.
Billy had formed an unusual bond with an orphaned Otter, who he later named Molly, with a documentary now airing that follows his incredible relationship with the wild animal.
Ahead of the interview, Cat wanted to make sure she was brushed up on her information so sat down to watch the National Geographic channel hit with her two children. However, she was overly enthusiastic and appeared to give some major details away - much to fans' dismay.
Taking to X - formerly Twitter, to call her out for ruining the series, one fan raged: "So Cat's spoilt then #thismorning."
"Thanks for the spoiler, Cat. Tell the whole story of the otter.....#ThisMorning," another complained while a third added: "THANKS CAT..just spoiled the whole story for everyone ffs!! #thismorning." (sic)
Someone else penned: "Things Cat didn't do last night number 1 #ThisMorning."
Meanwhile, other viewers were so taken with the beautiful story and glorious surroundings in Shetland, that many even contemplated relocating. "Googling 'moving to Shetland' as we speak #ThisMorning," said one viewer.
A second said: "It looks incredibly peaceful there, i'm ever so slightly jealous."
Cat explained that she'd streamed the series on Disney + before it went live on the National Geographic channel "today at 3 p.m." but couldn't resist revealing key details.
She excitedly told Dermot: "My boy's were like, 'he's made her a ball pit, it's amazing''," later on in the same conversation, the host also revealed: "And, she also meets a boy otter called Bozzo, and also has a baby," leaving fans reeling.
Billy and Molly: An Otter Love Story will stream on Disney+ on 14 November and air on the National Geographic channel on November 15. It will follow the incredible way in which Molly changed Billy's life, too.
About his first encounter with Molly, Billy recounted seeing her nibbling on a crab but seemingly not darting away when he approached. He told Cat and Ben: "Curiosity got the better of me, and I decided to see how close I could get."
He knew something was not right after Molly appeared not to shy away and knew that another female otter had been killed in the area recently. The animal lover explained: "She stopped eating, looked me right in the eye, and then went back to it.
"I thought 'that's not right, a wild otter should've run away at that point'," he exclaimed. "She was really thin and emaciated, but she wasn't unhealthy - she was just hungry."
Billy sought the advice of a local wildlife sanctuary, which advised him that feeding the animal was okay, provided he didn't domesticate her in any way. At this point, he started leaving Salmon in a box, and their relationship blossomed into something spectacular.
This Morning airs weekdays on ITV1, from 10am.
