Rob Lowe on Partying Days with Charlie Sheen: "We Competed to See Who Could Play Harder"

Back in the '80s, Rob Lowe and Charlie Sheen competed frequently — but not for movie parts.

"We competed to see who could play harder, then show up for work and still kick a--," Lowe tells Vanity Fair. "The verdict: Charlie by a nose."

Charlie Sheen hopes Rob Lowe replaces him on Two and a Half Men

Lowe, who recently finished his autobiography, shared excerpts with the magazine. In the book, he calls Sheen "one-of-a-kind ... a Polo preppy clotheshorse in a world of O.P. shorts and surf T-shirts" and "a wonderful mix of nerd ... and rebel.""At my house, we are still saving money by not buying desserts," Lowe says. "At Charlie's house, it's never-ending Haagen-Dazs, brand-new BMWs, a lagoon pool with underwater tunnels, and a lit, professional-grade basketball half-court."The two are still friends, and Sheen recently gave Lowe the thumbs-up when the actor was rumored to be a top candidate to replace him on Two and a Half Men. Parks and Recreation executive producer Mike Schur, however, says Lowe is not leaving Pawnee, Ind., anytime soon.

Lowe also writes about his Outsiders co-stars in his book, calling Tom Cruise — then a houseguest of the Sheens — "open, friendly, funny" with an "almost robotic" focus; Patrick Swayze "as cool as you want"; Matt Dillon "a young ladies' man"; and Diane Lane a "legend" at 16.
