Johnny Depp splashed out on the 45-acre tropical paradise in the Caribbean after discovering it by chance on a family holiday.
"Like everything else in my life, it wasn't planned, it just kind of happened. After I had done the first Pirates movie, I went on vacation to escape with my kiddies and my girl and someone said there was an island down the road for sale. I looked at it, I walked on it and I was done.
"So I immediately called my business manager and said 'Please!' And that was it," he told Britian's Daily Telegraph.
The actor uses the island to spend quality time with his family away from the media, The China Daily reports. "It came at the perfect moment. The island provides me with somewhere I can go where no one is looking at me or pointing a camera or a finger at me. When we're there we do absolutely nothing. My kiddies don't have any toys there and they build little houses out of shells," he added.
Depp has two children with girlfriend Vanessa Paradis.
