It seems like a lifetime ago, but Britney Spears fell in love with Kevin Federline, and even broadcast it on a WB reality show, Britney and Kevin: Chaotic.
The five-episode reality series, culled from home videos during the European leg of her Onyx Hotel Tour, was skewered by critics and its ratings tanked.
Speaking to the UK's Telegraph, Spears says that it was a big mistake to put her love life on camera like that. The biggest mistake she's made, in fact.
"I would never do something like that again," she says. "Actually, that was really bad. That was probably the worst thing I've done in my career."
Asked if she feels the same way about 2002's film Crossroads, Spears clutches her hand to her heart. "No!" she shouts. "I like Crossroads! F--k you!"
