Jennifer Lopez came out fighting on Friday September 6, as she made her first public appearance since news of her divorce filing from Ben Affleck emerged in a very risque gown.

For her red carpet debut at Toronto International Film Festival, the actress boldly rocked a silver mirror embroidered column dress from Tamara Ralph, with cut out detailing, featuring black silk velvet bows.

She wore her hair loose down her back, and notably was not wearing her wedding ring.

Jennifer stars in the new film Unstoppable, which was produced by Ben and his BFF Matt Damon; Ben chose not to attend the red carpet but Matt Damon was there, with his wife Luciana, who wore a slinky black gown with a plunging sweetheart neckline.

Unstoppable follows the true story of Anthony Robles – who was also on the red carpet – who defied expectations to become a champion wrestler in college, competing against the very school that rejected him.
