It's man vs. boy!
David Arquette, 40, and Rob Kardashian, 24, and the rest of Season 13's Dancing With The Stars cast celebrated the season's halfway point at STK Lounge in Beverly Hills Tuesday night.
But at the soiree, while David looks dapper in a suit, Rob dressed down in a sweater and baseball cap. Rob has some growing up to do!
Of course, even a celebration can be a little nerve-racking. Arquette Tweeted, "#DWTS being at a Dance Party with professional dancers is an intimidating prospect". Give yourself some credit, David! You've made it this far!
Also at the party were Derek Hough and Mark Ballas. While Hough looked handsome and playful, Ballas seemed angry (he and partner Kristin Cavallari were eliminated early on.) See the photos after the jump!
The two reportedly met up with Derek's ladylove Lauren Conrad after leaving STK!
