Ashlee Simpson jumped on the braid bandwagon and headed to Las Vegas this weekend to watch her man Pete spin at the Grand Opening of Palms Place Hotel & Spa on Saturday night. It was a family affair with Papa Joe and Jess in the house, and while Tony skipped the event, he was right by Jessica's side in San Diego yesterday. Lauren and Lo left The Hills long enough to attend the event, while Sarah Larson had to walk the red carpet all by her lonesome, poor baby. Pete kept the crowd entertained with dedications to his "baby mama" and father-in-law, but we're going to have to wait to hear more of Ashlee's musical stylings — she unsurprisingly postponed her Summer tour to get ready for her new baby.
