Lindsay Lohan is covered in blood and holding a knife in a provocative new photo obtained by RadarOnline.com.

Don't worry, she hasn't murdered anyone and she probably isn't a vampire either, it's a new picture released by the innovative photographer Tyler Shields.

The 25-year-old star is shown in all her bloody gory, channeling Megan Fox from Jennifer's Body, holding a knife while she's drenched in the blood.

Lindsay Lohan had a low-key birthday celebration Saturday night. Passing on any sort of wild party, Lindsay opted for dinner out in Malibu with her sister Ali, brother Michael Jr., and a few friends.
