Britney Spears Slams Ex Kevin Federline? Reveals 'Chaotic' Reality Show Was 'The Worst Thing' She's Ever Done (VIDEO)

Britney Spears' career has been filled with high and lows, including a very public mental breakdown. However, Spears looks back at one decision she made in her career as her biggest mistake: her reality show "Chaotic".

"Chaotic" was a joint reality show with then-husband Kevin Federline. The show documented their marriage for five episodes before it was canceled. The couple divorced in 2007.

"I would never do something like that again," Spears told the Telegraph U.K. "Actually, that was really bad...[Chaotic] was probably the worst thing I've done in my career."

However, the 32-year-old Pop star has come full circle from her "Chaotic" days. Spears has landed herself a two-year show run at Las Vegas' Planet Hollywood. The singer will reportedly earn $300,000 a night, according to the Telegraph. The show's run is set to begin on Dec. 27.

"Vegas is definitely a new challenge," she told the Telegraph. "But I wanted to be able to put on a different type of show. You get to do so much more when you don't have to put your stage in trucks after the show every night - we got to build a venue specifically for my show. It's going to be more like a party than a typical concert."

To add to the pressure, Spears is also releasing her eighth studio album "Britney Jean". According to the Telegraph, the singer is a self-proclaimed "perfectionist," who is "nervous" about the release of her upcoming album. Spears claims she needs more rehearsals now then she did in the beginning of her career to prepare for her performances.

"The increased scrutiny does make me a little harder on myself these days," she said. "There are more expectations of me now, not just in terms of what I do, but also in terms of who I am."
