These 10 stars once floated our boats. Now they give us a sinking feeling ... 

It's that testosterone-y time again -- the time when People magazine gets all hot and bothered as it anoints the new Sexiest Man Alive. But sexiness, like fame, can be fleeting.

Nick Nolte, 67: Yeah, we were just as dumbfounded as you to realize that People declared Nick Nolte the Sexiest Man Alive in 1992, a year in which competition was apparently slimmer than Victoria Beckham in airtight Spanx.

Mickey Rourke, 52: There was a time when Mickey Rourke was so seductive that he could entice a blindfolded Kim Basinger to devour the entire contents of her fridge, and make it rain blood while having sexy times with Lisa Bonet. 

Jude Law, 35: A few weeks before Jude Law was named Sexiest Man Alive in 2004, he poked fun at his comeliness on "Saturday Night Live," singing, "I took one look in the mirror / And I could clearly see / That there was one perfect thing in it / And that thing was me ... / I ... moredon't need to really act / I don't need a big heart / I don't need to be nice / I don't need to be smart."

Val Kilmer, 48: It's not that we expect Val Kilmer to sport the same glistening, muscular physique he showed off as Iceman during that shirtless, homoerotic-subtext-laden volleyball scene in 1986's "Top Gun." But we do expect that he not let himself go to the point where we're... more concerned for his health. 

Tom Cruise, 46: When Tom Cruise was named Sexiest Man Alive in 1990, his "Rain Man" co-star Valeria Golino rhapsodized over his eyes, "not their color. His regard -- the way he looks with them. They're very alive.

 Vince Vaughn, 38: A good sense of humor can go a long way to making a man attractive, so it's not surprising that Vince Vaughn has been skating by on his ability to make us laugh and our long memories of just how cool, funny, and easy on the eyes he was in his breakthrough ... morerole as the beautiful-baby-wooing Trent Walker in "Swingers."

Mel Gibson, 52: It's a testament to Mel Gibson's former sex-symbol standing that he could strut around in a weapons-grade mullet in several of those "Lethal Weapon" movies and still be considered gorgeous. And gorgeous he was, with his dreamy blue eyes and self-assured swagger... more helping him land People's premiere Sexiest Man Alive cover in 1985, a Sexiest Classic honor in 2002, and a Sexiest Man With the Most Kids (seven) nod in 2005.

Jared Leto, 36: "I just like how he's always leaning. Against stuff. He leans great." So sighed Angela Chase as she mooned over Jordan Catalano on "My So-Called Life." Leto's portrayal of the archetypal high school bad boy -- he skips class, he's in a band, he drives a fast ... morecar -- granted him instant heartthrob status and helped land him on People's 50 Most Beautiful People list in 1996 and 1997. 

Russell Crowe, 44: Russell Crowe was named one of the "Awesome Aussies" in People's Sexiest Man Alive issue in 2000, the same year he won over audiences (and inspired many an appreciative Maximus Hunkiness quip) with his rippling-muscled, Oscar-winning performance in the ... moretunic-tastic "Gladiator." 

Wesley Snipes, 46: In its 2005 Sexiest Man Alive issue, People saluted Wesley Snipes as one of the "40 fabulous men" who are "sexy at any age." That's probably not an honor the fallen star will brag about when he begins serving his three-year prison sentence for failing to file... more tax returns (assuming his appeal is unsuccessful).
