Grace Van Dien is no "stranger" to the red carpet.
For the premiere, which took place at Roy Thompson Hall, the 25-year-old looked chic in a black velvet mini dress with a fitted bodice.
To accessorize her glamorous ensemble, the daughter of "Starship Troopers" star Casper Van Dien opted for a black choker with a pearl pendant, delicate silver rings, dangling earrings and an elegant pearl headband.
For glam, "The Village" actress donned a glossy pink lip, rosy cheeks and thick black eyeshadow. Her golden locks were styled in a loose chignon with curls that framed her face.
To walk the red carpet, Van Dien was joined by her 90s heartthrob father, who wore a black suit and a black dress shirt.
The actor added a pop of colour to his outfit with a leopard print tie and matching shoes.
The father-daughter duo smiled for the cameras and waved at fans as they made their way down the carpet, clearly having the time of their life.
Later on, Grace was also pictured giving her father a tender hug while he looked upon her with pride.
On Twitter, fans went crazy over Van Dien's "stunning" look.
"It's Grace Van Dien's first appearance at the Toronto International Film Festival but it's her happiness captured through the lens of her fans that you can almost feel radiate from the screen, that's the tweet," penned a fan.

"Biggest crush at the moment," a Twitter user added.
"Grace Van Dien slayed the red carpet with her look. She is the sweetest and most humble person," shared a fan.
"It's Grace Van Dien's world and we are all just living in it," penned another with the heart eyes emoji.
