In an interview with the U.K.'s Telegraph, Britney Spears reveals her biggest career regret: Britney and Kevin: Chaotic, the reality show she filmed with her then-husband Kevin Federline.

"I would never do something like that again," Britney said about the show. "Actually, that was really bad. That was probably the worst thing I’ve done in my career." No offense to Brit, but we're pretty sure she's not the only one who thinks that. 

The five-episode series aired on UPN in 2005 and was almost unanimously panned by critics. The show included many intimate moments with the couple, including Britney talking about their sex life and a lot of farting and burping.
