Britney Spears won't allow kids to enter showbiz

CEBU, Philippines - Britney Spears said she is crossing her fingers that her two children won’t want to follow in their famous mom’s footsteps.

“If my sons told me they wanted to be in the entertainment business, I’d lock them in their rooms until they turned 30,” she tells the August issue of Cosmopolitan, according to People.com.

Spears, 28, wants sons Preston, 4, and Jayden, 3, to avoid the downsides of fame that she’s had to deal with since her youth – like having paparazzi trail her every move, though acknowledges the attention is “something I always knew would come with the job I chose.”

Nevertheless, the 28-year-old pop singer and former “Mickey Mouse Club” child star said she’s glad that her sons with ex Kevin Federline have instead expressed an interest in martial arts.

“They just started karate class, which is super cute,” Spears said, People.com reported.
