Jennifer Lopez made a stunning return to the spotlight at the Toronto International Film Festival (TIFF) on Sept. 6, attending the premiere of her new film *Unstoppable*. This event marks her first major public appearance since her split from husband Ben Affleck on Aug. 20, after two years of marriage.

At 55, Lopez dazzled on the red carpet in a striking floor-length silver dress by Tamara Ralph. The sultry gown featured high splits on both sides, tied together with oversized black velvet bows, and showcased her daring side-boob cutouts. She completed the look with a matching metallic Judith Leiber clutch, Dolce & Gabbana platform heels, and eye-catching Hassanzadeh jewelry.

Her sleek, straight hair with a middle part only accentuated the boldness of her look, drawing all eyes to the daring ensemble. Lopez’s appearance comes in support of “Unstoppable”, a film she co-produced with Affleck, 52, under his and Matt Damon’s production company, Artists Equity. *Unstoppable* tells the inspiring true story of wrestler Anthony Robles, born with one leg, who won a NCAA national championship in 2011. Lopez plays a supporting role as Anthony’s mother, Judy.

Though Ben Affleck, who co-produced the biopic, was notably absent from the event, Lopez commanded the evening, celebrating the film and her incredible style in true JLo fashion.
