Zac Efron made his first public appearance at the amfAR Gala during the 81st Venice International Film Festival on September 1, following a 'minor swimming incident' in Ibiza on August 2. Efron, who looked stylish in an all-black outfit, was seen mingling with other celebrities, including Richard Gere, who was honored with amfAR's Award of Inspiration. The Gala, hosted by Kate Beckinsale, also honored Antonio Banderas and Mohammed Al Turki and featured performances by Kelly Rowland and Rumer Willis. Efron had been hospitalized as a precaution after ingesting water into his lungs during a dive, but was released the next morning after X-rays confirmed no water remained in his lungs. He later reassured fans of his recovery by posting a photo of himself lifting weights with the caption 'Happy and healthy. Thanks for the well wishes.'
