J ohnny Depp and girlfriend Amber Heard are to marry this weekend on his private island in the Bahamas - and the actor 'can't wait'.

A source reportedly told E! News that Mortdecai star Depp, 51, is 'completely in love' with his 28-year-old fiancée and the pair are preparing for a low-key ceremony this weekend.

The couple, who got engaged in December 2013 after meeting on the set of The Rum Diary in 2011, will marry at Depp’s home on his private island, Little Hall’s Pond Cay in the Bahamas.

Around 50 guests will attend the intimate ceremony on the Caribbean island, which Depp purchased in 2004.

Depp is no stranger to a celebration, having thrown a massive medieval themed party at Carondelet House, Los Angeles to celebrate their engagement with VIP attendees including Marilyn Manson and Steven Tyler.

But with accommodation thought to be limited on the island, Heard's family and Depp's two children with ex-partner Vanessa Paradis - Lily-Rose, 15, and Jack, 12 - will be staying on his yacht during the celebrations.

A source said the pair are in a 'good place', despite rumours of a split and are planning the February nuptials to work around their busy schedules.

The source added: 'She's filming a movie in London, and he's getting ready to film the next Pirates of the Caribbean in Australia. So this is the only time that everyone could get together.'
