Johnny Depp and Amber Heard are engaged, it has been reported.

The couple, who met on the set of The Rum Diary in 2011, have been dating since June 2012, shortly after Depp revealed his split from partner of 14 years Vanessa Paradis. 

Depp and the French actress and singer are parents to daughter Lily-Rose, 14, and son Jack, 11, but never married. 

A source confirmed the news to People, saying: "Of course they couldn't be happier to be engaged and excited to share the rest of their lives together," adding that Heard has told "close friends" about their engagement.

According to reports, Depp gave Heard a diamond engagement ring some time ago, but the couple have remained quiet on their news.

The actors have not yet commented on the reports, however the rumours were initially sparked when Heard was spotted wearing a diamond ring on her engagement finger while out in Hollywood this week.

Heard will next be seen in the crime thriller London Fields later this year, which will see Depp make a cameo appearance. The film is based on Martin Amis's 1989 book of the same name and will also feature Billy Bob Thornton, Theo James and Jim Sturgess.
