Britney Spears couldn't say what her song "Oops!...I Did It Again" was about during her appearance on James Corden's Carpool Karaoke on "The Late Late Show" Thursday night.
"I think it's just a song," she said.
Spears sang many of her famous hits dating back to the '90s during her ride with Corden, who harmonized and belted out the tunes while in the driver's seat.

The two sang hits from "Oops!...I Did It Again" to "Toxic" to "Baby One More Time."
During the ride, Spears said she wanted three more children — without the baggage of a partner.
"I think I might not ever go to men again," she said. "I think, ever do the whole men thing again anymore. I'm just done with men."
She continued, "I don't believe in marriage anymore."
Spears paid tribute to her first hit by sporting a gray cardigan and white oxford shirt that echoed her famous schoolgirl uniform from the music video.
Spears noted that she employs some subterfuge when staying at hotels by using aliases.
One example is "Anida Dick."
Britney's Carpool session was timed with her new album, "Glory", which officially released right before she stepped into Cordon's car.
"Glory" marks Spears' ninth studio album and the pop star released the first single off the highly anticipated body of work back in mid-July with the track "Make Me."
Spears recently spoke to E! News about the making of the album.
"It's very exciting...I've been working on this project for a year and a half now, almost two years so it really means a lot to me," she said. "It's my baby."
"It's a little melodic, a little more not so poppy," she added. "It's kind of chill. Very chill."
