The 34-year-old singer’s edition of the viral hit series from The Late Late Show will air on Thursday night (August 25).
In the preview clip, James asks Britney if her kids have seen her Vegas show and when she says yes, he says he saw his mom in her underwear when he was 11.
Britney hits James‘ arm and calls him “so dirty,” but he replies and says, “I’m not dirty. I can’t shag the image from my brain.”
