Christina Aguilera is living it up after filing for divorce from husband Jordan Bratman -- and spent this weekend partying in Hawaii!

Christina looked sexy without her wedding ring at two different events for the opening of the Waikiki Edition hotel in Honolulu.

The hotel opening was a star studded affair: "True Blood's" Ryan Kwanten and "Entourage" star Kevin Dillon attended as well -- while Vanessa Hudgens, Shenae Grimes and Whitney Port all showed off their bikini bods on the beach!

Check out all the hot Honolulu sightings!
