TIFF 2013 Red Carpet: Celebrities Act Silly And Look Hilarious (PHOTOS)

The Toronto Film Festival has almost wrapped up another celebrity-packed season (we're waiting for you, Jennifer Aniston!) and while we're sad to see Hollywood leave, we're glad we get the chance to look back on all the memorable moments.

TIFF 2013 saw a major influx of stars invade the city including Brad Pitt, Julia Roberts, Kate Winslet, Scarlett Johansson, Sandra Bullock and Taylor Swift. (We could go on for days.)

While they walked the red carpets, schmoozed with the media and took photos with fans, the celebs mostly maintained bright picture-perfect smiles. But not always. On the rare occasion, they let their guard down and got a bit silly (we're looking at you, Joseph Gordon-Levitt), and fortunately, photographers were around to capture the action.

Check out the most hilarious pics of celebs at TIFF 2013:
