Kylie Jenner's birthday milestone has taken on a life of its own. In the midst of celebrating with pals and boyfriend Tyga in Punta Mita, Mexico, the reality star gave her Instagram followers a closeup of their vacation on Friday. In her latest snap, Kylie lounges near a pool in a revealing one-piece bathing suit. "Relax w meee," she wrote. Earlier this week, the group soaked up the sun on a boat day.
