Britney, 34, talks about her two sons in the clip as James quizzes her about whether they have seen her Las Vegas show.
"I saw my mum in her underwear once when I was like 11," he reveals, before Britney interrupts by saying: "You're so dirty."
James replies: "I'm saying it's not dirty, I can't shake the image from my brain."
It remains to be seen whether Britney can surpass the reigning Queen of Carpool Karaoke, Adele, whose appearance has attracted 123 million views on YouTube.
