Jessica Simpson isn’t avoiding her 28th birthday on Thursday – she’s already started celebrating. The singer – joined by close friends and family – indulged in her favorite cupcake flavor, red velvet, from Crumbs bakery. For dinner, Jessica and on-again beau Tony Romo went to Sagebrush Cantina in Calabasas, where they met up with her pregnant sister Ashlee and husband Pete Wentz. At one point, Ashlee and Jessica got on stage to sing with The Copycats, a cover band that was playing. The band serenaded Jessica with “Happy Birthday.” Following dinner, Jessica and Romo hit Key Club in West Hollywood to see Steel Panther (formerly known as Metal Skool). The Dallas Cowboys quarterback even tried his hand at singing the Guns n’ Roses hit “Sweet Child O’ Mine” to Jessica and the crowd.

Actress Vivica A. Fox, Rage Against the Machine singer Tom Morello and Hancock director Peter Berg were all also in the Key Club audience last night for Tony’s performance. It really sounds like things are back on track and in full swing for Jessimo. It takes a lot for a guy to get up on stage and embarrass himself in front of a bunch of people with crappy singing just to impress a girl (twice — he sang to her at Key Club back in January, too) … I guess it must be love … lucky for Papa Joe Simpson ;)
