Watch Britney Spears Join James Corden for 'Carpool Karaoke'

Singer and 'Late Late Show' host talk kids and hotel aliases, wear schoolgirl outfits for "...Baby One More Time"

Britney Spears is the latest pop artist to sit shotgun with 'Late Late Show' host James Corden for "Carpool Karaoke."

Britney Spears was the latest pop artist to sit shotgun with current Rolling Stone cover star James Corden for "Carpool Karaoke." The pair cruised around singing Spears' hits like "Toxic," "Womanizer," "Oops!... I Did It Again" and Glory single "Make Me."

During the ride, Spears revealed that she wants to have three more kids in addition to her nine- and 10-year olds. "All that she wants is another baby," Spears sings impromptu, quoting Ace of Base. But she hasn't found the right guy yet. When asked who her ideal man is, Spears said: "I think [I won't] ever do the whole men thing anymore, or get married. I'm just done with men … I may French kiss someone, but I won't ever get married."

Spears also disclosed some of the "tons" of aliases she's used when she stayed in hotels: Anita Dick, Alotta Warmheart, Chastity Montgomery. "I might start just checking in as 'It's Britney, bitch,'" Corden says.

The "Carpool Karaoke" session ended much like how Spears' career began: With the singer – and Corden, with wig and pigtails – donning a schoolgirl outfit and singing her career-launching hit "...Baby One More Time."

Watch how James Corden became late-night TV's king of celebrity sing-alongs, one 'Carpool Karaoke' at a time.
