She's no stranger to the red carpet, and last night (September 10) Megan Fox was spotted at a screening of "Jennifer's Body" at the Toronto International Film Festival.

The "Transformers: Revenge of the Fallen" actress was joined by costar Amanda Seyfried at the Midnight Madness event, held at the Ryerson Theatre.

And Miss Fox was looking absolutely fabulous as she posed for the paparazzi in a sexy strapless black dress with a ruffled hemline.

Coming up on September 26th, Megan will be kicking off the 35th season of "Saturday Night Live" with musical guest U2.

Enjoy the pictures of Megan Fox promoting "Jennifer's Body" (September 10).
