Matthew McConaughey and Lance Armstrong are playing it straight.
In an interview in the November issue of Details magazine, the fast friends and frequent workout buddies addressed rumors about their sexuality and denied they were gay.
"We tried it. Wasn't for us," McConaughey joked.
"It's like, either you sleep with anything that moves or you're gay," Armstrong added.
Speculation about the nature of the well-muscled duo's relationship began after they, along with Jake Gyllenhaal, were frequently photographed in each other's company, often shirtless, while off in one athletic pursuit or another.
"I think people see pictures and think we're these overgrown frat guys, but we all have those kinds of relationships—and relationship isn't a bad word," Armstrong told the magazine. "I mean, we all have buds, we all take guy trips, but you take something very normal and you put it in a magazine, and people start talking."
Armstrong said he thought he and McConaughey became close so quickly because they had both ended relationships—Armstrong with Sheryl Crow and McConaughey with Penélope Cruz—right around the time they became friends.
"Our friendship just kind of developed," the seven-time Tour de France champ said of the man he refers to as the Redneck Buddha. "He got out of a relationship; I'd just gotten out of a relationship."
In the absence of significant others of the opposite sex, the pals had more time to dedicate to male bonding.
"I'd do anything he asked me to, even though he'd probably never ask me to, and he feels the same way," McConaughey said. "It's fun going out and living life and doing things at the drop of a hat. LiveStrong just happens to be the most deliberate guy I’ve ever met."
When they're not biking, rock climbing, running or engaging in other sweaty activities, both McConaughey and Armstrong have film projects in the works.
McConaughey is set to reteam with his How to Lose a Guy in 10 Days costar Kate Hudson in the upcoming comedy Fool's Gold. Production on the film is slated to begin this month.
Armstrong will reportedly star as himself in a feature film based on his autobiography, It's Not All About the Bike: My Journey Back to Life. The movie is expected to be released next year.
