James Corden texted Leo DiCaprio from J Lo’s phone and it was GAS

Jennifer Lopez was in the hot seat last night for James Corden's Carpool Karaoke and we certainly got more than we bargained for.

While the presenter was scrolling through her contacts – which included Chris Brown, Bradley Cooper and Cristiano Ronaldo – he came across Leonardo DiCaprio's number and exclaimed: "I'm going to text Leo!"

He proceeded to text: "Hey baby, I'm kind of feeling like I need to cut loose, any suggestions? Let me know." And then James brilliantly signed off the message: "J.Lo (you know, from the block)."

After showing the camera Jen's phone to prove the text was legit, Leo replied and said: "You mean tonight Boo Boo, club wise?"

James, clearly excited, declared: "You're going to the club with DiCaprio!"

We're sure Jen had a bit of explaining to do after the show was over, but one thing's for sure, it gave us a good laugh.
