Britney Spears, who is pregnant with her second child, says she's not ready to retire from performing.

"I can't wait to do that again," Spears, 24, tells Harper's Bazaar in its August issue, on newsstands July 25. "But I really have to take my time and do it right and be safe. Actually ... not that safe. When you perform, you have to be dangerous."

The pregnant pop princess also says she would "definitely" consider a musical collaboration with her husband, Kevin Federline, 28. His debut hip-hop album, "Playing With Fire," is expected to be released next month.

"I'm so proud of Kevin," Spears says. "He's been working so hard on his own album since I got pregnant with Preston," the couple's first child, who was born last September.

"Preston's just like a rocker kid," she says of her 10-month-old son. "He is a beautiful baby. We're very close, and attached."

Spears, who darkened her hair and posed naked for the camera of lensman Alexi Lubomirski for the Bazaar photos, says her first pregnancy made her feel "paranoid" because she was new at everything.

"This one, I was like, I just gotta wing it. It was weird for me at first because of who I am; wherever you go they expect you to look a certain way. I'm not supposed to be this huge pregnant superstar."

Spears plans to get back into fighting shape after Baby No. 2 — due this fall — is born.

"After this baby, I'm going to get really intense with it."
