LOS ANGELES -Johnny Depp and Amber Heard are engaged. The pair, who has been together around 18 months, is set to tie the knot, Us Weekly reports.

‘The proposal happened a while ago,’ one insider said. ‘She just didn’t wear the ring.’ Johnny first met his bride-to-be on the set of their movie The Rum Diary. They confirmed their relationship in June 2012, shortly after Depp announced his split from longtime love Vanessa Paradis, with whom he has two kids, daughter Lily-Rose, 14, and son Jack, 11.

Later this year, the couple will reunite onscreen in London Fields, a crime thriller based on the 1989 novel of the same name by Martin Amis. Depp has a cameo on the movie, which also stars Billy Bob Thornton, Jim Sturgess, and Theo James. Two days before, Johnny Depp bought Amber Heard a ‘commitment’ ring. The 50-year-old actor, who has been dating the beauty, 27, for two years, has fuelled speculation that they are set to marry after buying her a bespoke platinum, black pearl and diamond ring which Amber wears on her engagement finger.

A source told The Sun newspaper: ‘’It’s a commitment ring and has an inscription on the inside in tiny writing which is a love note from him to her. No one’s seen him this head-over-heels ever, he’s like a different guy. ‘’All his angst has gone and for once he seems anchored and happy. They’re starring in a film together later this year and wherever she goes, he goes. They’re never apart for long now.’’  The actress was seen hiding the finger of her left hand as she entered a Los Angeles restaurant.

According to E. News, Amber and another woman dined at Ago, and as she left the star did everything she could to hide the ring from waiting photographers. Amber and Johnny first met when they starred in 2011’s ‘The Rum Diary’ but didn’t get together until after the breakdown of his 14 year relationship with Vanessa Paradis, with whom he has Lily Rose,14, and Jack, 11.
