Selena Gomez lounged in a bikini and shared a picture of the relaxing afternoon on Twitter, writing, "Need sun again." She's in the Sunshine State to film Spring Breakers with pals Vanessa Hudgens and Ashley Benson. They've been busy on set since last week, but Selena got away from production to celebrate her boyfriend Justin Bieber's 18th birthday on the West Coast over the weekend. Selena and Justin showed PDA during the bash, which was also attended by Ashley Tisdale and Carly Rae Jepsen. Justin kept the fun coming last night when he attended a Drake concert in LA with friends. Drake and Justin have apparently been working on new music, since they were snapped in the studio together just last month.
