"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 the Huffington Post.
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."
Another topic she isn't looking forward to discussing with her two boys: the birds and the bees. "I'm dreading the moment when my sons ask me how babies are made," she tells the magazine.
But for now, Spears is just enjoying life with her boys who recently graduated from preschool.
"Things are pretty quiet right now," she says. "I've been spending a lot of time at home with my boys. They just started karate class, which is super cute!"
