While reading my morning guilty-pleasure blog, Celebritology, I came across a post that referred readers to All Property Management, which recently listed, in its blog section, a number of celebs who own islands, along with a few details about each island. With the way the press hounds celebs, no wonder they want to get away from it all. According to the post, private islands really cost (um, we knew that), with the owner buying the land, supplying their own water and electricity, creating a waste disposal system and building a dock or an airstrip. Also, don't forget security -- if you're off filming or do-gooding or having twins in France, you can't leave the island unattended.

Here's the list of celebs the post cited as island-owners: John Lennon, Marlon Brando, Mel Gibson, Johnny Depp, Nicolas Cage, Tim McGraw and Faith Hill, Gene Hackman, Robin Williams, Tony Curtis, Richard Branson, David Copperfield, Leonardo DiCaprio and Athena Onassis. See the gallery for a few of these retreat spots.
