Mischa Barton wasn't about to let her recent DUI arrest get in the way of celebrating her birthday - but this time she was smart enough to hire a driver! Mischa celebrated her 22nd birthday on January 24 with an intimate party in her hotel room at the Sundance Film Festival. "It was just her mom and a few friends," the insider says. The next day, Mischa hosted friends for a dinner party at Casa Vega in LA, where according to the insider, Mischa and her pals drank margaritas and partied until heading over to Benny Medina's 50th birthday party at his house on the Sunset Strip for champagne.
