Of all James Corden's many Carpool Karaoke videos, few were as entertaining as his ride with Jennifer Lopez. In one of the segment's funniest moments, James sent a hilarious text to Leonardo DiCaprio from Jennifer's phone asking about where she could "cut loose" that night. His response — "You mean tonight, boo boo? Club wise?" — immediately went into the Carpool Karaoke Hall of Fame, and the "Feel the Light" singer revealed how Leo reacted to the prank while sitting down with James on Thursday night. "He wasn't mad at all! I was afraid he would be mad when it all came out, but he was so cool about it," she assured him. "I guess he calls every girl boo boo, I don't know."
