We're afraid we can't give you must detail on this one, but we can say for certain that if you're out on a Bahamian beach - if you can even find one, given that they all appear to be owned by celebrities - you might just see a pretty woman standing on the opposite coast on her own island nearby. Julia Roberts definitely owns an island somewhere in the Bahamas - probably quite close to her famous friends - but has never let slip on the precise locations.
To be honest, we can understand that. We probably wouldn't want photographers and paparazzi bothering us on an island we'd paid millions of dollars to own, either. As we're unable to bring you a photo of Roberts on her island, here's a picture of her looking suitably summery in front of a background that may or may not be her island. It's as close as we're ever going to get!
