Britney Spears choreographs dance routines for her sons.

The 'X Factor' judge revealed her two kids with ex-husband and former dancer Kevin Federline - Sean Preston, seven and Jayden James, six - have natural talent and love to work on dances she puts together for them to Snap's 'Rhythm Is A Dancer' and Justin Bieber's 'Baby'.

She told America's ELLE magazine: "I have to kind of guide them a little bit, but for the most part they remember it. They like to rock out."

Britney also admitted Sean already harbours hopes of being a star but she is unsure if she wants them to follow her into the entertainment business.

The pop beauty - herself a former child star - said: "Jayden is too young to really see if he's interested in being famous. But Sean Preston, he really loves to dance.

"I feel like in most situations, when that happens it's because the mom or dad is influencing it and pushing it a little bit. Otherwise, they wouldn't be going to that many auditions because the kid's too young to know. Any time you see a child star, it's mainly because of the parents. If they love to perform and dance on stage, if that's their thing, then of course you don't want to keep it from them, their dream. But then again, it's hard."
