Jennifer Lopez isn’t too cool to carpool…

The 46-year-old Puerto Rican singer, actress and American Idol judge helped Late Late Show host James Corden celebrate one year on the air with a memorable appearance on his Carpool Karaoke Primetime Special.

Corden’s first order of business with la Lopez was to settle on nicknames. “You’re J.Lo, I could be J. Co,” he suggested.

“I think we should make a rap group together!” Lopez said, adding that they could open for her in Las Vegas.

“Yeah, but I worry about you having to follow it,” said Corden. “I worry the audience are like, ‘Aw that’s a shame that he’s gone.'”

Sitting shotgun, Lopez taught Corden her “music video look” and showed off some impressive contacts in her phone (Leonardo DiCaprio, Demi Lovato, Bradley Cooper and Iggy Azalea among them), or “the best phone I’ve ever seen in my life.” Corden even texted DiCaprio as her, inconspicuously signing it “J.Lo, you know, from the block.”

They also sang “Love Don’t Cost a Thing” and “Booty“, then J.Lo. beat on Corden while singing her Spanish-language hit “Que Hiciste,” as well as discussed the possibility of insuring parts of Lopez’s body.

Corden’s “Carpool Karaoke” segment has become a viral hit in late night, with celebrity appearances including Adele, Justin Bieber, Elton John and One Direction bringing more than 800 million views to the Late Late Show’s YouTube account. Late Late Show producers are already exploring a spinoff series based on the segment.
