When Jennifer Lopez appeared on James Corden’s The Late Late Show Carpool Karaoke Special, the two played a prank: Corden texted Leonardo DiCaprio from Lopez’s phone, telling him she wanted “to cut loose.” He responded by asking if she meant “tonight, boo boo? Club-wise?” Later, Lopez had to explain to him that she didn’t mean any of it.

“He was a great sport about it,” she told reporters after Thursday’s American Idol, Entertainment Tonight reports. “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.”
