Britney Spears is the latest celebrity to do “Carpool Karaoke” with James Corden on The Late Late Show.

Britney Spears Carpool Karaoke

Corden and Spears kicked off their Carpool Karaoke session with the Britney classic, “Oops! I Did It Again.” When Corden pressed Spears about what the song is really about, Spears claimed to not actually know, that it’s just a song. Spears was more definitive when it came to talking about expanding her family – she wants three more kids, but is done with the idea of marriage.

Spears and Corden went on to sing “Womanizer” and “Toxic” and talk about her sons – Sean, 10, and Jayden, 9 – seeing her in the racy outfits she wears in her Las Vegas shows. Spears reassured Corden that her sons can separate that out as “mommy performing.”

Spears also informed Corden about some of her past aliases – Anita Dick, Chastity Montgomery, Alotta Warmheart – how she got “paddled” in the first grade, and that she recently heard from a friend that some men get aroused by getting tickled for a long period of time.

Spears and Corden completed their Carpool Karaoke session with “Baby One More Time” – and Corden in pigtails.
