Cruz Beckham, Posh and David's youngest son who turns three tomorrow, totally stole the Spice Girls' Madison Square Garden show when he broke out his awesome B-boy moves during "Mama."
After trying to keep a straight face during the song, Posh proudly announced, "He's the next Justin Timberlake!"
It's absolutely adorable, the perfect pick-me-up if you're having a rough morning and cute celebrity children bring you endless amounts of joy like they do us.
