Alex Rodriguez’s birthday party had nothing on Jennifer Lopez’s bash

Days after Jennifer Lopez celebrated her 50th birthday with an over-the-top Miami party — her fiancé, Alex Rodriguez, celebrated his own 44th with a more intimate affair at his Miami home.

Spies said A-Rod had about 100 friends and family members over at his Miami estate.

Last week, Lopez had a wild party at the home of Gloria Estefan on Star Island, Page Six reported, with guests including DJ Khaled and Fat Joe.

At his bash, A-Rod got on the mike and joked, “JLo, you don’t know nothin’ about this Miami s–t right here!” a video post of the party revealed.

He was then seen dancing in a circle of friends when “Hustlers” star Lopez — in Daisy Duke cutoffs — backed up and was grinding against him as the crowd chanted, “Go JLo!”

“It was a wild night,” said a friend.

Lopez also gave the ex-Yankee a birthday shoutout at her Miami concert, and delivered him a birthday cake to the broadcast booth during “Sunday Night Baseball.”
