Britney Spears may have found a two-pronged solution for keeping her kids as innocent as possible. "If my sons told me they wanted to be in the entertainment business, I'd lock them in their rooms until they turned 30!

The 28-year-old mother of two says in the August issue of Cosmopolitan. And that's a good place for them to be if no one tells 'em about the facts of life.

"I'm dreading the moment when my sons ask me how babies are made," the pop princess adds as she talks about mommyhood and playing (or, these days, avoiding) the fame game.

The pop princess' interview with Cosmo, during which she talked joyfully about sons Sean and Jaden, comes on the heels of yet.

Another round of rumors about Spears' supposedly suspect parenting skills (that have all been denied by those close to her, FYI).

But just because a storm is almost always brewing outside, Spears appears to have found the calm within. "Things are pretty quiet right now. I've been spending a lot of time at home with my boys," shes says. "They just started karate class, which is super cute!"
