The 28-year-old actress and 51-year-old actor held a second ceremony on the beaches of Depp's private island, Little Hall's Pond Cay. Heard and Depp wed for the first time at their home in Los Angeles last week.
Sources told Us Weekly only a few dozen guests were in attendance, including actor Paul Bettany, Depp's two children, 15-year-old daughter Lily-Rose and 12-year-old son Jack. Heard wore a long-sleeved wedding gown with an exposed back and a long veil, according to People.
"Johnny's private island is a tropical paradise," an insider told the magazine. "Wedding guests were treated to an amazing weekend that ended with a romantic beach ceremony ... Everyone seemed to have the best time. It was a very celebratory vibe."
Heard and Depp met on the set of The Rum Diary in 2009, and started dating shortly after the actor ended his relationship with longtime partner Vanessa Paradis in 2012. The couple confirmed their engagement in April 2014.
Heard last starred with Kevin Costner in 3 Days to Kill, and will appear in a number of upcoming projects, including London Fields with Depp and Magic Mike XXL with Channing Tatum. Depp is scheduled for Black Mass with Dakota Johnson and Yoga Hosers with daughter Lily-Rose.
