The birthday party dined on Chilean sea bass, crispy rise and tofu lettuce wraps. When the clock struck midnight, a special berry cake from a L.A. was delivered to the birthday party. A toast of Patron Platinum for the now 21 year old was in order.

After midnight Rumer led the party upstairs to TAO Nightclub and continued the fun. They headed to the VIP Moat section where Holly Madison, Robert Earl, Soleil Moon Frye and her husband, Jason Goldberg, Ashton’s business partner held court.

Las Vegas enjoys excess so a second cake was delivered to Rumer with a happy birthday song from an Elvis impersonator and several colorful showgirls. A Madonna impersonator made her way to Rumer and delivered a bottle of Cristal. Did you know Rumer and Madonna share the same birthday?
