Rob Lowe shows off his fit figure on the new issue of Vanity Fair, and the 47-year-old actor shares snippets from his book Stories I Only Tell My Friends: An Autobiography and chats about everyone from Charlie Sheen to Tom Cruise.

On being competitive with the Two And A Half Men star, Lowe told the magazine, "We competed to see who could play harder, then show up for work and still kick ass." Lowe added that Sheen is a "one-of-a-kind" guy, who he describes as "a Polo preppy clotheshorse in a world of O.P. shorts and surf T-shirts." Hmm, funny how he doesn't address his pal's recent media meltdown!
