'Britney Spears: I Am the Femme Fatale' Trailer -- Watch It Now!

Pop star gives fans an intimate look at her life in the special airing Sunday at 9 p.m. ET on MTV.

This Sunday at 9 p.m., "Britney Spears: I Am the Femme Fatale" makes its world premiere on MTV. In the special, the singer offers an intimate peek inside her world, taking fans behind the scenes of her big nightclub show in Las Vegas and chatting with MTV News correspondent Sway about her life and career.

The MTV special follows Britney as she makes her way into the studio to listen to "Big Fat Bass," produced by Black Eyed Peas frontman will.i.am, who tells Spears, "I did some tweaking to the 'Big Fat Bass'; the bass is even bigger."

Spears later explains the difference between recording tracks versus performing them live. "When you're in the studio, you're just really focused, you're really in your head and in your ears and on the notes," she explains. "And when you're performing, it's more a connection on the outside and more of — like a tiger and more in your body."

The pop star says it's fans who fill the audience at those live shows who get her excited to perform. "When they're screaming like that, they just hype you up," she says, "and make you feel larger than life."

Spears has been a public figure since she was on the "Mickey Mouse Club" as a kid, and in 2011, she turns 30 years old. In the special, Spears admits that she wanted to be a famous performer since she sported a schoolgirl uniform in her " ... Baby One More Time" video nearly a decade and a half ago. "I think I hoped I would be [doing this]," she says. "I genuinely love what I do. This is what I love to do."
