Amber Heard engaged to Johnny Depp?

'The Rum Diary' star Amber Heard has sparked engagement rumours with Johnny Depp after she was spotted with a huge diamond rock on her left hand.
The 27-year-old bisexual actress, who is said to be in a relationship with the superstar, caught the eyes of paparazzi while she was leaving a restaurant recently with the ring, reported E! Online.
According to a source, Heard and another woman dined at Ago, and as she left the actress did everything she could to shield her left hand from photographers.
She even waited for a valet driver to open her car door so that she did not have to show her ring finger.

Amber and Depp, 50, first met when they starred together in 2011's 'The Rum Diary'. The duo reportedly made their official red-carpet debut as a couple recently at the Art of Elysium gala at LA's Skirball Center.
