Before he made it big as Captain America, Chris Evans was best known in some circles for an incredibly sexy 2004 Flaunt photoshoot. In fact, the skin-baring photos became such a big deal that Chris' publicist actually advised him against doing more spreads of that kind.

What's It Like To Be Naked With Chris Evans?

"I really didn’t think twice about taking my shirt off at the time, but my current publicist would pull her hair out if I did that photo shoot today," he told The Advocate in 2009. "It never really occurred to me that that could be misinterpreted as a bad thing or as selling out. But I hired my publicist for her professional opinion, and she seems to think it's a mistake. I have no problem taking my shirt off for a role if the part calls for it, but my publicist says, 'When you're promoting yourself, being you, there's a way to keep it as classy as possible. Greasing yourself up and stripping down may not be the best way to do it.' To some degree, she may have a point."

Fans couldn't have disagreed more. They felt like, "He's got it -- flaunt it". But for the last 8 years, Chris has kept his shirt on, off-screen. Until now.

Clearly content enough that people now know he is an actor first and a pin-up second, Chris happily took it off for the May issue of Details Magazine. And while you'll have to wait until April 24 to snag the copy on newsstands, Insider.com has a sneak peek behind the scenes of the shoot.

Three New Avengers Clips

In the video, you can also hear Chris give Details a few details about his personal life -- from his worst audition (Gone Baby Gone) to his celebrity crush (Sandra Bullock), Chris has an answer for (almost) everything. He's even adorably forthcoming while discussing how Captain America differs from the other Avengers: "Captain America has no business being on this squad. Iron Man is shooting missiles, Thor is calling down lighting, Hulk is ripping apart jets and I'm taking the stairs. It's really unfortunate. It's too bad [but] it's what the movie requires and that's OK."
