Even as a supporting player, Johnny Depp is unfailingly gallant. The actor, 50, is usually the star of the show on red carpets, but on Wednesday he was at L.A.'s Arclight Theatre to support his fiancée, Amber Heard, at the premiere of her new film, 3 Days to Kill. Far from being shy, the couple engaged in some Pda, as Depp stole a kiss from his bride-to-be before they headed inside for the screening. Both were strikingly dressed, too, with Heard, 27, looking gorgeous in a long-sleeve dress with a deep neckline and high slit, and Depp quite dapper in a navy three-piece suit and hat.
