Selena Gomez jetted to Cabo San Lucas, Mexico, to celebrate her bachelorette party with her closest girlfriends, a source exclusively confirms to Us Weekly. "It was a very fun but chill weekend," the source shares. "These girls have been close to her for over a decade now, so it meant the world to her to celebrate these moments with them." In addition to a boat day, the group enjoyed "private dinners with a chef and a villa to themselves with plenty of lounging in the sun," according to the source.
