Here’s What Happens When J.Lo and James Corden Send Leonardo DiCaprio a Text During Carpool Karaoke

James Corden’s “Carpool Karaoke” is right up there with “Mean Tweets” as the most entertaining late-night sketch of all time, and last night Jenny from the Block herself hopped in the car, and it was downright glorious.

Jennifer Lopez and Corden sang a medley of her hits (along with a Bruno Mars tune), but she also dished on her—count ’em—five engagements and scrolled through her phone to name-check all the famous people she’s friends with (Demi Lovato, Duane “the Rock” Johnson, Iggy AzaleaBradley Cooper).

When Corden asked if he could text one Leonardo DiCaprio with a “hey baby, I’m kind of feeling like I need to cut loose—any suggestions?” a mortified J.Lo said absolutely not, but—spoiler alert!—he did it anyway, and a reply came in within minutes: “You mean tonight, boo boo, club wise?”

So many amazing things about this: First, Leo actually took the time to type “boo boo”; and second of all, the Oscar winner clearly thought she was serious. Watch the whole amazing 13 minutes above.
