LOS ANGELES, Calif. -- In addition to launching her seventh studio album, "Femme Fatale," Britney Spears has a demanding schedule being a mom to her two sons.

"I'm usually pretty busy when I'm not working," the 29-year-old pop princess said during an interview on MTV's "Britney Spears: I Am the Femme Fatale," which aired on Sunday.

"I have two children, so I usually get them up in the morning, and I'm usually at the gym, and I help cook dinner sometimes ... a lot of the stuff that I do I do early in the morning when my boys are at school," she said of Sean Preston, 5, and Jayden James, 4.

Despite being one of music's biggest stars, Brit likes to get in front of the stove occasionally.

"I help cook dinner sometimes. I'm not that much of a cook, but I help," she said. "I try a little bit of everything, but I don't have a special dish."

Britney, who turns 30 in December, said she's glad to still be in the spotlight.

"I think I hoped I would be [doing this]," she said of her career. "I genuinely love what I do. This is what I love to do."

She might love her job, but she wasn't too fond of the recent shoot for the video for "Femme Fatale's" second single, "Till The World Ends."

"The set was a little much. It was grimy and gross and it felt like there was poop everywhere when there wasn't," she said of the video shot in a warehouse in Los Angeles. "It was sweat and it was disgusting sometimes ... [I] tough it out,"

And according to Brit, she's not looking to step down from her duties as the Princess of Pop anytime soon.

"I hope so," she said when asked if she wants a long career, like role model Madonna. "Or maybe [I'll be] doing nothing!"

As previously reported on AccessHollywood.com, "Femme Fatale" is reportedly set to debut at the top of the charts this week, according to Billboard. Britney has been making the rounds lately to promote "Femme Fatale," with recent performances in Las Vegas, San Francisco and an appearance on "Jimmy Kimmel Live" last week.
