 "It's not softcore porn, hunny, it's called ART." 
 
 That's how Lindsay Lohan describes her recent photo shoot where she's covered in blood and a bra, holding a gun to her head. 
 
 It's certainly not something her dad would like, and the rest of the Twitterverse isn't too happy about the pics, either. People are calling them crazy, perverse and even a cry for help. 
 
 But they really are meant to be art, photographer Tyler Shields tells E! News exclusively. 
 
 "To me, it's not that big a deal, but I can understand that it's a big deal to other people," he says. "She's participating in an artistic adventure. This is not just her running around on the streets with a gun."

 His project is a book called The Dirty Side of Glamor, which Shields describes as "people doing crazy things in a crazy way" and compares the shoots to filming scenes in a movie. 
 
 More importantly, it was Lohan who contacted him about participating and, while Shields conceptualized the shoot itself, she knew the kind of macabre things would be in store. 
 
 "She wanted to be a part of what I was doing," he says. "When someone comes to me and they've already seen my work and already know what it is, nine times out of 10, they knew what they're getting into and they know what they're going to be a part of and they want to do it." 
 
 Shields says Lohan was gung-ho for the duration of the experience—before, during and after the camera started snapping. 
 
 "There was not any diva behavior at all to me," he claims. "But also she wanted to be a part of what I was doing and I'm sure that makes a difference." 
 
 We're just happy she's not dressed—or undressed, for that matter—as Marilyn Monroe again.

– They don't call her 'Linsanity' for nothing: Lindsay Lohan tweeted a picture of herself yesterday clad in black lingerie with a gun pressed against her lips. But don't worry: "It's not softcore porn, hunny, it's called ART," she explained. The photographer agrees, telling E! Online that she's "participating in an artistic adventure." The Huffington Post has 'behind the scenes' footage from the photo shoot, which shows more gun poses and shots of the actress lying spread-eagle, smeared with blood. The TMI tweeting doesn't stop there. Late yesterday, the actress engaged in a Twitter war with her ex, Samantha Ronson. "I'm pretty sure that @samantharonson just threw a fit @33years old," wrote Lohan. "Jack and crack will make for some crazy tweets," Ronson responded. "If you're gonna be an idiot an do coke- do it outside the bathroom- some of us actually use them to pee in." Click here to read more of Lindsay's troubles.
