Johnny Depp and Amber Heard have been dating since April, and fans were disappointed that Amber Heard didn't join Johnny Depp for the London premiere of his new film "The Lone Ranger." However, his girlfriend attended dinner with him later that evening with co-stars Armie Hammer and his wife Elizabeth Chambers.

Johnny, Amber, Armie, and Elizabeth had a celebratory meal at C restaurant, Perez Hilton reports.

Amber Heard, 27, stayed out of the spotlight earlier that evening, but joined Johnny, 50, for a double date looking just as ready for the red carpet. She wore a stunning satin red dress paired with deep red lipstick and an up 'do, as well as snakeskin heels.

Depp held Amber's hand as he escorted her to the restaurant wearing a dark suit, blue shirt, and his blue shades, The Daily Mail reports.

Armie opted for a surprising red suit that challenged Amber's dress. His wife Elizabeth wore a plain black dress cinched at the waist with a sequined black belt.

Entertainmentwise.com reports that Johnny Depp admitted to The Sun that he still maintains a close relationship with his ex-girlfriend of 14 years and mother of his two children, Vanessa Paradis, despite their split last June.

At the London premiere, he told The Sun: "Vanessa is a good mother and a wonderful woman. There really are no hard feelings between us. We have remained very close and I hope to maybe be able to make a film with her one day. Why not?"

Let's hope Amber doesn't mind! Heard and Johnny met on the set of "The Rum Diary" in 2011 and were rumored to be involved before they took their relationship public in April, Entertainmentwise.com reports.

Bruce Willis and his wife Emma Hemingway were also at the restaurant enjoying dinner together that evening.
