Spears discussed her time as a musketeer while visiting The Ellen Show Tuesday, where Ellen Degeneres asked her about an alleged kiss she shared with Ryan Gosling while the two played Spin the Bottle.
"I did that, but I didn't kiss him though," Spears told DeGeneres. "The only person I kissed was Justin [Timberlake.]"
When Degeneres asked why she never kissed Gosling, Spears explained that the bottle simply "never landed on him."
"He's a liar," Degeneres said of the Drive star, who supposedly told her he had kissed Spears. "He's good looking, but he's a liar."
Spears, who turned 32 on Monday, was visiting the talk show to promote her latest studio album Britney Jean, out Tuesday, and to publicize her Vegas residency tour Britney: Piece of Me, which kicks off December 27.
"It's probably the hardest show that I've ever done. I'm dancing the most I ever danced," the singer said of her 90-minute performance, which will take place in Sin City's Planet Hollywood four nights a week.
"It's gonna be a lot of fun!" she added.
