Among the many festivities over the weekend to officially launch summer 2013 was Sunday's exclusive dual birthday celebration of "Dancing With The Stars" pros Derek Hough and Cheryl Burke. Hosted by Cîroc Ultra-Premium vodka, guests were invited to a gorgeous Hollywood Hills home overlooking the city below for the pool party. There, they enjoyed ringing in our favorite season with dips in the pool filled with beach balls, hanging out in the sun and shade on lounge chairs, sipping refreshing Cîroc cocktails, and indulging in some of Derek and Cheryl's birthday cake.
