Leo, ever the gentleman, responded in kind: "You mean tonight, boo boo? Club-wise?"
Any other time, we're sure the two would have been seen getting down on the dance floor, but this time, DiCaprio took Lopez's intended joke seriously. So, how did J Lo explain the prank to the Oscar-winner?
"He was a great sport about it," the singer said after Thursday’s American Idol, according to ET. "I was like, ‘So, hey, this is what had happened. I was with James Corden...’ He’s great. He’s a friend, and it was nice."
Lopez went on to say that Leo was, in true Leo fashion, pretty chill about it:
"He was totally like, ‘Do whatever you want, I don’t care,'" she said. "I don’t know if he’d say that today!"
So it looks like there was no partying after all, but we're not feeling too bad about it.
We're sure Leo has plenty of club buddies to fill the lonely nights.
