Sydney Sweeney Glams Up at 'The Voyeurs' Premiere with Justice Smith!

Sydney Sweeney got all dressed up on Tuesday night (August 25) to celebrate the premiere of her movie The Voyeurs alongside co-star Justice Smith!

The two stars were picture perfect on the red carpet at the event held at NeueHouse in Los Angeles.

Also in attendance at the premiere were co-stars Ben Hardy, Natasha Liu Bordizzo, and Katharine King So, as well as writer and director Michael Mohan.

Here’s a synopsis of the movie, which premieres on September 10: When Pippa (Sweeney) and Thomas (Smith) move into their dream apartment, they notice that their windows look directly into the apartment opposite – inviting them to witness the volatile relationship of the attractive couple (Hardy, Bordizzo) across the street. But when they attempt to anonymously intercede in their lives, they unwittingly set in motion a chain of events that will lead to disaster.

Sydney‘s grandmothers were extras in the movie and they attended the premiere, which meant they were present to watch her intimate moments on the big screen.

“Yeah, it’s probably not the most grandma-friendly movie to watch,” Sydney told Variety. “But then my grandma also thought it would be great to bring her son – my uncle. I couldn’t say no. So it’s my uncle, my aunt, my two grandmas, my mom and a couple of friends who are here. I did tell them there are going to be some moments where you have to cover your eyes and ears. They did. Actually, my Nana sat there going, ‘Whoa!’”

It was reported that at one point during the movie, Justice was heard yelling, “Don’t watch, mom!”

FYI: Sydney is wearing a Dior dress. Ben is wearing Saint Laurent.
