Britney Spears' son, Sean Preston, shakes his groove thing

Proud mama Britney Spears captured her son Preston (6) dancing along to Peaches & Herb's disco classic "Shake Your Groove Thing" while playing a video game. Luckily for us, Spears posted the clip to YouTube and Twitter and the rest, is, indisputably cute history.

Sean dances along, following cues to wiggle his hips and wave his hands around. He's momentarily distracted when little brother Jayden (5) attempts to drive a Big Wheel through his dance floor. He quickly pushes the interloper aside and finishes his big number.

And with two parents who know a thing or two about dancing (dad is former Spears back-up dancer-turned-rapper Kevin Federline), Sean clearly has it in the genes.

"Dancing with the Stars," we hope you're watching. Three words: youngest contestant ever?
