Lilo, Photographer Defend Gun Photos as 'Art' Plus, she and Sam feud on Twitter By Emily Rauhala, Newser User Posted Apr 30, 2010 7:12 AM CDT 7 comments Comments Bad behavior. (Screen Grap) (Newser) – 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.
