At the Comic Con party for Megan Fox‘s upcoming movie, Jennifer’s Body, the Transformers star showed up in a simple but sexy black dress that showed off her collection of tattoos.

The actress showed off the body she lent out to demonic possession for the Diablo Cody horror flick on the red carpet. The film is set to premiere at the Toronto Film Festival during the Midnight Madness installment of the event.

Yup, that’s right, folks. When the movie opens on September 18, you’ll get a chance to see these in motion.
