Johnny Depp is set to tie the knot next week

Los Angeles - Johnny Depp and Amber Heard will reportedly marry next week.

The Mortdecai actor and his 28-year-old fiancee - who got engaged in December 2013 after a year of dating - are planning to tie the knot on his island in the Bahamas over the weekend of 7 to 8 February in front of just 50 guests.

Accommodation on the 45-acre Little Hall's Pond Cay island is so limited, many of the guests - which will include the bride's family and Johnny's two children from his relationship with Vanessa Paradis, Lily-Rose, 15, and 12-year-old Jack - will be staying on the 51-year-old actor's yacht during the celebrations.

The couple chose the date because of their hectic working schedules.

A source explained to the New York Post Newspaper's Page Six column: "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.''

Amber will wear a dress designed by Stella McCartney for the wedding ceremony, the insider claimed.

The couple - who met on the set of their 2011 movie The Rum Diary - celebrated their impending marriage with an engagement party last March.

The medieval-style bash, at Carondelet House in Los Angeles, was attended by the likes of rockers Marilyn Manson and Steven Tyler, movie producer Jerry Bruckheimer and singer Mandy Moore.
