When Spears reveals that they’ve seen her racy Las Vegas show, Britney: Piece of Me, Corden quips that he saw his mother in her underwear when he was 11, prompting her to feign disgust as she slapped him on the arm: “You’re so dirty!”
Spears’ Carpool Karaoke will be featured on Thursday’s Late Late Show, which airs at 12:37 a.m. PT/ET on CBS. Her new album, Glory, hits stores Friday.
