We want to throw it back to an O.G. hunk who had us creaming our jeans in the '70s and 80s: Ryan O'Neal. With his wavy hair, boyish face and fit figure Ryan was a total dreamboat in his heydey.

He was born asCharles Samuel Eldridge Patrick Ryan O'Neal III which is a mighty name that he grew into with his 6'1" frame. He was an amateur boxer who began his career in Hollywood as a stuntman. He had his breakthrough role in 1964's Peyton Place. From there he starred in Nickelodeon (1976), Paper Moon (1973), Barry Lyndon (1975) and his Oscar-nominated role in Love Story (1970). He was a busy boy in the swingin' seventies.

And he truly was. He really got around the block in 70s Hollywood, having relationships withpretty much every hottie in Hollywood. He has been linked with Jacqueline Bisset, Oona Chaplin, Barbara Streisand, Diana Ross, Anjelica Huston, Ursula Andress, Bianca Jagger, and Farrah Fawcett (whom he was engaged to before her death) just to name a few. Seriously, that's just a few, but it's enough to have a stellar Divas Live reunion. We're sure Ryan still has the energy and sexual prowess to keep a woman or a man happy!

We loved him most in the gay cop comedy Partnersin which a straight cop has to go undercover with a gay cop as a couple to solve murders that are affecting the gay community. It isn't the most PC portrayal of gay men in the movies, but Ryan is tight leather pants is a sight to behold.

His co-star Steven Reischwas also a sexy sight who almost showed his penis by just barely cupping his crotch.

Ryan himself said that Hollywood lost interest in him after the 70s. He called himself "a glamour boy, a Hollywood product" according to his IMDB. However, glancing at his resume on there it looks like he's kept himself busy. He had a starring role in Bones (2006) and was recently announced to be taking a part in The Waste Lands. Yes, he acts less and less and he doesn't show any skin, but Ryan is hard at work. We hope that this self-proclaimed glamour boy returns to his pretty boy roots and takes off some clothes or dons some leather one last time.
