Britney dreams of stage

"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.

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, according to the AP.

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