Late Late Show host James Corden celebrated one year on the air with Jennifer Lopez on his Carpool Karaoke Primetime Special

The show kicked off on Tuesday with "Primetime," Corden and Reggie Watts' version of Macklemore & Lewis' "Downtown." "I went to my network boss and said screw it. My boss was like, 'How about a special? You want to do it?'" Corden rapped. "I'll make your TV shine brighter than a halo. All leading up to a carpool with J.Lo." He had teased the special earlier on Tuesday, featuring the rap and the special Carpool Karaoke appearance by Jennifer Lopez. 

Corden's first order of business with the American Idol judge 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, for example), 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", and discussed the possibility of insuring parts of Lopez's body. 

Earlier in the episode, Corden introduced the special episode with an encore of his most-viewed segment yet, Carpool Karaoke with Adele, which has racked up more than 89 million views on YouTube to date. The Adele episode features the duo singing "Hello," talking about Adele's love for the Spice Girls and deciding once and for all that Adele is "the female Phil Collins." 

Crosswalk: The Musical followed, with Corden's "theatrical event" that he first debuted last April in Los Angeles. Corden and his company performed "Summer Nights," "Greased Lightnin' " and "We Go Together" at the intersection of Beverly Blvd. and Genesee Ave. 

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.

The Late Late Show Carpool Karaoke Primetime Special aired on Tuesday at 10 p.m. ET/PT on CBS.
