It’s hard to keep a secret in Hollywood, and although  Amber Heard was seen trying to cover up a diamond ring  on her left hand on Monday, she doesn’t need to hide it anymore – PEOPLE has confirmed that she’s engaged to  Johnny Depp.

“Of course they couldn’t be happier to be engaged and excited to share the rest of their lives together,” a source tells PEOPLE, adding that Heard has “told close friends” the news.

“Amber has really taken well to the kids and really enjoys spending time with them. And she’s even taken Lily shopping on her own for some bonding time.”

The couple, who met on the set of their 2011 movie The Rum Diary went public with their relationship the following year after Depp, 50, announced his split from partner of 14 years Vanessa Paradis.
