Britney Spears New Back Up Dancers: Jayden James & Sean Preston
As the offspring of all-singing, all-dancing pop star Britney and a dancer father Kevin Federline, it's no surprise the children are already honing their moves.
Sean Preston, three, and Jayden James, two, were spotted showing off the dance skills as they performed an impromptu routine to their mum's hits Toxic and ... Baby One More Time.
The two boys were videoed frolicking along to the song during a soundcheck at London's O2 Arena on Tuesday night - 24 hours before their famous mother took to the stage herself.
In the video, older brother Sean, dressed in a grey t-shirt and checked shorts, frequently attempts to do cartwheels and handstands as he kicks his little legs up behind him. His little brother Jayden, who is just 12 months younger, prefers to keep his action focused inside a gold hula hoop as he spins around like a ballerina.
