Britney Spears was one of the most highly-anticipated Carpool Karaoke guests – and she didn't disappoint! The 34-year-old pop star belted out some of her biggest hits as she made her debut alongside James Corden on Thursday, kicking things off with her 2000 song, Oops!...I Did It Again.
In between verses, James quizzed Britney on the meaning of the track's lyrics. "Ermmm, I don't really know! I think it's just a song!" she admitted, before James told her, "I think of it everytime I order a Domino's (pizza)!"

After performing the track, mum-of-two Britney got personal as she revealed to James that she would love to have more children. "I want to have more, like three. But I have to find the right guy first," she said. She then admitted: "I think I might never do the men thing again, I'm done with men… I might French kiss someone, but I'm not going to marry anyone. I don't believe in marriage anymore."
It was the perfect introduction to her number one song Womanizer, which was followed up by her new single Make Me and Toxic. But the best moment came when the pair got together to sing her 1998 breakout smash song, Baby One More Time, complete with matching school uniforms and James in a braided pigtails.
Britney's fans were treated a sneak peek at her carpool earlier this week in a clip showing her duetting on the 2003 song Toxic - but nothing could have prepared them for the hit-filled full-length version.
She is the latest in a long list of high-profile stars who have joined James for a spin in his car, including Mariah Carey, Adele, Elton John, Chris Martin, One Direction, Justin Bieber, Gwen Stefani, Stevie Wonder and, most recently, First Lady Michelle Obama, who sang along to tracks including Beyoncé's hit Single Ladies, and Get your Freak On with Missy Elliott.
