Sure, her music career may have all but fallen off the map, and she went kinda nuts after having a couple children with that sleazy back-up dancer -- but Britney Spears is making a comeback.

She's been lip syncing to performing her old material at clubs around the country, promoting a new fragrance, and promises to have cleaned up after that unfortunate, bald-headed trip to rehab.

But is it only a matter of time before Brit self-destructs again?

At a recent photo shoot for her new perfume, "She got very upset and stormed out and wouldn't come back," a source tells the NY Post's Page Six. Apparently the former pop icon is "taking control of her life," but has gone completely overboard, "not listening to anyone and doing exactly what she wants."

None of this makes it seem like a comeback is in the cards. However, a different source -- completely unrelated to either Britney or her record label -- claims there are at least "four definite hits on the next album." So maybe, if she can keep from imploding until the new album is released, Brit might just have a second shot at stardom.
