Britney Spears' two young sons have snatched the spotlight from the superstar - showing off their dance skills in new footage posted on their proud mum's website.
Pint-sized Sean Preston, three, and Jayden James, two, demonstrated their best moves at a soundcheck for Spears' Circus concert at London's O2 Arena on Tuesday (02Jun09).
The boys, whose dad is former back-up dancer Kevin Federline, were spotted performing an impromptu routine with hula hoops, break-dancing, cartwheeling and kicking to their mum's hits Toxic and ...Baby One More Time.
The talented twosome are cheered on by dancers and crew in the videos uploaded online - but no one was as proud as the star herself.
She writes on her Twitter.com page, "Check out the newest addition to my show on BritneySpears.com. Hope you love 'em as much as I do!"
