Caught! Sam Worthington as a Biker Babe!

Avatar star makes mouths drop

Did Avatar hottie Sam Worthington buy a badass motorcycle to match his new action hero heartthrob persona?

Nope (tho we kind of think it would be totally sexy!) The strapping hunk—who tends to prefer a dressed-down Joe Schmoe look off the set—was spotted walking his regular ole bicycle down the street in West Hollywood.

But S.W. drew attention in another way, and our sneaky WeHo spy says an ambulance almost had to be called the scene.

What the heck went down?

Turns out that Sam is so drop dead gorgeous (as if we didn't already know, personally)—sweaty in workout clothes with manly unshaven scruff and mischievous eyes—that our stunned source almost fainted at the sight of him.

The always friendly S.W. smiled and said, "Hello, mate" to our gushing gab, only causing him to fawn more over the too-yummy star.

Hey, we can't blame our day-dreaming disher—Sam is definitely one of our fave new studs too. Can't wait to see him don leather and kick ass in the superhyped Clash of the Titans.

Another muscle man that caused less of a scene...

Nick Lachey, who got his BBQ on at Virgil's Barbecue in New York. The beef-muffin, wearing a T-shirt and jeans, seemed to want to fly under the radar for the evening. He and his entourage asked to be seated to the side on the upper level of the restaurant, where the group dined quite discreetly.

Not to be rude, but we're pretty sure it's fairly easy for the ex-Mr. Simpson to avoid attention while eating out—has he even done anything relevant lately? Unless hosting that lame-ass The Sing-Off counts (which, let's be honest, it doesn't).

And for a less buffed-up boy out on the town...

Entourage's very bitching Rex Lee was caught getting a bit of work done in South Florida. But wait—he's not going the way of some of our favorite divas (or, better yet, some of our not-so-loved reality show stars).

Rocking a pair of gray jeans and a black hoodie, Ari Gold's MVP was seen going into the Millennium Laser Eye Center in Sunrise for his appointment. Lee was superhappy to be getting the eye upgrade, and happier still to have a male friend by his side to help him back to the car afterward.
