The 45-year-old former MLB player was seen getting cozy in a booth with a young blonde on Friday night.
J Lo's ex-fiancé was all smiles as he leaned in to capture a selfie with the stunner over dinner.
He even shared it to his Instagram Story, seemingly flaunting his fun night in his former almost wife's face.
He looked pretty comfortable with the blonde who called A-Rod "the big boss."
His big night out comes just hours after it was revealed the ex-Yankee slid into a married woman's DMs.
Australian TV host Belinda Russell addressed the incident on-air ahead of the weekend, revealing A-Rod messaged her complimenting her on her Instagram "feed."
"I woke up this morning, checking the socials and in my requests there was a message from Alex Rodriguez. As in A-Rod. As in J.Lo's ex," Russell told her co-host and the world.
"All I can say is... he likes great content, Dickie. He just said, 'great feed!'" she added, trying to play it down.

The problem with Rodriguez's flirty DM is Russell is happily married with kids.
Our sources tell us A-Rod is not impressed with how fast his ex-fiancée moved on with her former flame Ben Affleck after their breakup.
After photos circulated showing her with Affleck in Montana, all bets were off.
“There has been a few angry emails and text’s, but Jen and Alex haven’t spoken in a week or so,” our source explained earlier this month.
"Despite telling him that nothing happened with Ben while Jen was still engaged to him, something is fishy," they added.
Montana wasn't the only time that J Lo and Affleck got together either.
