Singer Kesha attended the The Humane Society of the United States gala at the Beverly Hilton hotel in Los Angeles, Calif., on Saturday night looking healthy and sexy in a see-through black gown. The pop star paired the glittering black dress with pink and green hair and a gold tooth.

It was the star's first public appearance since spending two months at the Timberline Knolls clinic in Illinois, where she addressed her bulimia and anorexia issues.

A close pal says Kesha recently moved to Los Angeles because she has "a great support system" to whom she "can talk to about anything."

She postponed her upcoming "Warrior" world tour following doctor's orders to overcome her issues before focusing on her career again.
