Johnny Depp hit the red carpet alongside his The Lone Ranger costar Armie Hammer for the film's premiere in London last night. After debuting the movie in the UK, he fit in romantic time with his girlfriend, Amber Heard, who accompanied him for the festivities in London. Amber wore a sexy red dress as Johnny took her by the hand for a dinner date at C London restaurant later that evening. This is not Amber's first stop on Johnny's worldwide press tour, since she also previously joined him in Moscow and Japan. Although it was just Johnny and Amber last night, the couple was accompanied by his children, Lily-Rose and Jack, for the Lone Ranger fun in Tokyo last week.
