Jennifer Lopez Wows in Eye-Popping Gown at “Unstoppable”'s TIFF Red Carpet While Ben Affleck Skips Premiere

Lopez made her mark in a showstopping look to promote the new film, in which she stars

Jennifer Lopez just made a fashionable impression on the Toronto Film Festival.

On Sept. 6, the global superstar attended the premiere of her new film, Unstoppable, an event that marks her first major public appearance since her split on Aug. 20 from husband Ben Affleck after two years of marriage.

Lopez, 55, lit up the carpet with her eye-catching ensemble. She donned a sexy floor-length silver Tamara Ralph dress with high splits up both sides, tied together with oversized black velvet bows and revealing her daring and sultry side boob.

She paired the look with a perfectly matching metallic Judith Leiber clutch and Dolce and Gabbana platform high heels, and Hassanzadeh jewelry. Her tresses were straightened with a middle part, bringing all the attention to her show-stopping dress.

Lopez gave fans an even closer look at her gasp-worthy look on Instagram, serving sexy poses as she showed off the number, her bare hips and side boob on full display.

"????Toronto #TIFF2024#UnstoppableMovie," she captioned the post, which also featured her giving a fierce face on the red carpet.

Unstoppable follows the real-life story of wrestler Anthony Robles, who was born with one leg and won a NCAA national championship in 2011 while competing for Arizona State University. Not only does Lopez have a supporting onscreen role as Anthony's mother, Judy, she also co-produced the biopic with Affleck, 52, under his and Matt Damon's production company Artists Equity. Affleck wasn't in attendance.
