Lo Bosworth  turns 22 today and had an early birthday celebration on Friday night at Tao in Vegas with Lauren Conrad  and a few of their friends. Audrina was also in town showing off that bikini bod  though it doesn't look like she was glued to her ex-roomie's  side. No trip to Vegas is complete without a little drama — Lauren looked a tad pouty talking to a boy in her Nicole Richie-style headband  while Lo found herself a man to make out with in the corner. Before we get more details on the party, we'll have to settle for the Stephanie and Doug drama on tonight's episode of The Hills .
