In a recent interview with The Telegraph in support of her latest album, "Britney Jean," and her upcoming residency in Las Vegas, Spears pinpointed her documentary mini-series "Chaotic," with then-husband Kevin Federline, as her biggest career blunder.
"I would never do something like that again," Spears told the publication. "Actually, that was really bad. That was probably the worst thing I’ve done in my career.”
"The increased scrutiny does make me a little harder on myself these days," Spears added. "There are more expectations of me now, not just in terms of what I do, but also in terms of who I am."
