Britney Spears' Sons Dance to Toxic (Part 1) from Britney Spears on Vimeo.

Move over Cruz Beckham, there're some new dancing tots in town.

Following in mommy Britney Spears and daddy Kevin Federline's footsteps (excuse the pun), Sean Preston, 3, and Jayden James, 2, put on a show of their own during rehearsal for Spears's "Circus" show in London Tuesday. Inside the ring, and using hula-hoops as props, the two had their own routine for mommy's hit, "Toxic."

We're wondering whom they inherited their dance moves from? Their pop star mama or back-up dancing papa?
