Britney Spears has revealed she does not want her sons to follow in her showbiz footsteps.

The pop singer wants her two sons - four-year-old Sean Preston and three-year-old Jayden James - to avoid the downsides of fame that she has had to deal with since becoming a global music megastar in her teens.

She told a US magazine: "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 attention] is something I always knew would come with the job I chose."

The 28-year-old says she has been enjoying some quality time with her boys.

"Things are pretty quiet right now. I've been spending a lot of time at home with my boys. They just started karate class, which is super cute!"
