Lindsay was back at the S Factor yesterday, perhaps practicing her "Helicopter" as she gets ready for her closeup...okay, a closeup on a "helicopter" is kind of a gross thought - but we're happy to see Lindsay happy and healthy and hard at work!

Lindsay was back to work yesterday on her film I Know Who Killed Me, where she plays an exotic dancer who develops split personality disorder. I have to say, when I first heard Lindsay was taking on this role and saw previous pix from the shoot, I thought no way could she pull off the role of a stripper, but now that I see her in full makeup and wardrobe, shooting at an actual strip club, I'm starting to believe it! And that isn't meant to be a dis, but a compliment - Lindsay looks hot and I can't wait to see her tackle this kind of role!!!

The ever-sexy Bruce Willis is showing the bad guys who's boss on the set of "Live Free Or Die Hard" yesterday in LA. Meanwhile, Demi was fighting evil forces of her own at a nail salon on Sunset just hours ago ...
