Leonardo DiCaprio sent his "boo boo" Jennifer Lopez a hilarious text message on the latest installment of James Corden's Carpool Karaoke.
The 46-year-old singer joined James for an hour-long Carpool Karaoke prime time special which aired on Tuesday night.
During their time together in the car, it was the superstar's celebrity-filled mobile phone that caused a stir with the host. When asked who the most famous person is in her phone, Jennifer pulled out her cell to show James the contact list, with names including Demi Lovato, Chris Brown, Bradley Cooper, Dwayne Johnson all featuring.
Footballer Cristiano Ronaldo got the most dramatic reaction from James though, who exclaimed: "Oh my God - hang on, I've got to pull in. This is the best phone I've ever seen in my life. This is insane. Fergie, Iggy Azalea."
James then found Oscar-winning actor Leonardo's number on the cell and proceeded to compose a text message. He kicked things off by writing "Hey Leo", before Jennifer interjected that she would never start a text with "Hey Leo".
After some debating, James composed a message which read: "Hey baby, I'm kind of feeling like I need to cut loose. Any suggestions? Let me know. J.Lo, you know, from the block."
While Jennifer laughed that she wasn't going to let James send the message, he had already done so. The pair then sang along to one of Jennifer's hit songs, On The Floor, by the end of which Leonardo had responded.
"He wrote back!" Jennifer laughed, to which James replied, "No way. No, he did not!"
Leonardo's response was classic, as Jennifer read out: "You mean tonight, boo boo? Club-wise?"
She giggled: "See, here's the funny part is that he actually thinks I'm serious!" And James added: "I love that he wants you to cut loose. This guy is the best."
However, Jennifer insisted she has more important priorities in her life than clubbing these days, telling James: "I'm totally not (going)! I'll be home cooking with my kids."
As well as her singing and acting career, Jennifer is famous for her curvy physique and, in particular, her prominent posterior. James also jumped at the chance to ask Jennifer about rumours she had her butt insured for $1 million, with the singer insisting the claims are entirely untrue.
"No! There is no such thing as that," she said. "I think there is a place in your homeland where you can insure certain things, parts of your body - seriously. I think that exists. I've heard that. Not here, I don't think!"
Jennifer also admitted she didn't see the point in insuring her derriere, or why it would be useful.
Here are five of our favourites:
The duo drove through the rain in London while Adele sung her hit Hello for the talk show host. They also discussed how Adele goes about getting a reservation and her friendship with Beyonce.
2. Iggy Azalea
Corden convinced the star to get out of the car and go wedding dress shopping with him. The duo bought the dresses and then proceeded to drive to the studio covered in white frills and lace.
3. Jennifer Hudson
The star took things a step further signing her hit Spotlight out of the car to a bus full of people.
4. Mariah Carey
Carey proved she was not only a great singer but also great with accents.
5. Justin Bieber
Bieber showed audiences he wasn't shy and belted out a few of his original hits, which he produced at the tender age of 15.
