There have been some great "Carpool Karaokes": Adele. Bieber. Sia. And now there's a new face on the "Carpool Karaoke" Mt. Rushmore: Jennifer Lopez. And a big reason for that is Leonardo DiCaprio.

Lopez was the guest of honor on The Late Late Show's Carpool Karaoke primetime special, and in between singing her hits like "Love Don't Cost a Thing" and "Jenny From the Block," the American Idol judge/Shades of Blue star and James Corden have a lot of goofy fun.

There's some enlightening stuff - J.Lo squashes the rumor that she's had her butt insured and says she's been proposed to five times. (She's only been married three times, though, and her marriage to Ben Affleck was called off, so who's the fifth?). But the highlight of show (and perhaps "Carpool Karaoke" in general) comes when Corden decides he wants to send a text to the most famous person in Lopez's phone.

Of course "Carpool Karaoke" might get its own show

His text message conversation with Leonardo DiCaprio must be seen to be believed. Check it out here:
