Britney Spears may have been trolled mercilessly on Twitter for the past days after the teaser for her Carpool Karaoke segment appeared to show her lip-synching to her own song, Toxic - but she's put those criticisms to bed with the release of the full video.
The singer can be seen singing along (very quietly) to a medley of her biggest hits with James Corden but the most eye-popping thing was the rather saucy nature of their exchanges.
Britney revealed some of the fake names she uses to check into hotels and, in move worthy of Bart Simpson, announced that she often signs in as 'Anita Dick' or 'Chastity Montgomery'.
The pair also discussed bondage in particular "a new bondage thing" of extreme tickling.
"They say, instead of bondage and hurting yourself, men get off on being tickled for a very long time" she said, before adding hastily "my friend told me". There's always "a friend".
The whole segment is part of a ramp-up of publicity before she makes her return to the MTV VMA awards ceremony after nine years and the release of her new album.
During her conversation, Spears also revealed that she is "done with men" and never plans to marry again. The singer was married to Kevin Federline from 2004 to 2007 and she had previously wed her childhood friend Jason Allen Alexander in Las Vegas but the marriage was quickly annulled.
However she said she hoped to have three more children in future if she finds "the right guy".
"I think I might not ever go to men again. I think I don't want to do the men thing any more or get married. I'm just done with men. I may French-kiss someone but I'm not going to marry anyone. I don't believe in marriage any more", she said.
The singer confirmed her sons, ten-year-old Sean and nine-year-old Jayden James, had seen her Las Vegas show. Asked what they think of the raunchier moves and outfits in the show, Spears replied: "I feel like they know that's mummy performing."
The topic also promoted Corden to tell Spears about the time he saw his mum in her underwear when he was about eleven years old. “I can’t shake the image from my brain,” he says, before receiving a friendly dig from Spears.
The pair also re-created Spears's music video for her breakout hit Baby One More Time, by dressing as schoolgirls, with Corden putting on a blonde wig and school uniform.
