Former lesbian actress Amber Heard has fueled rumors she is engaged to Johnny Depp after she was spotted wearing a large diamond ring on her wedding finger.

Fresh reports suggested The Rum Diary co-stars became engaged over the Christmas holidays, however, neither of them commented on the story and Heard was subsequently seen hiding her left hand in front of photographers.

Nevertheless, she has now been snapped showing off her new piece of jewelry, a gigantic ring on her wedding finger, fuelling speculation the pair is planning to marry.

On Saturday night, Heard was seen wearing the band as she photographed her rumored fiancé while he was on stage at a concert in Anaheim.

Devoted musician Depp was performing at the Servite Theatre with stars including Aerosmith's Steven Tyler, Alice Cooper, and Marilyn Manson, while Heard snapped pictures from the side of the stage.

The actor split from his long-term partner in 2012, Vanessa Paradis, the mother of his two children.
