Here's How Sydney Sweeney's Grandma Reacted to Nudity on 'Euphoria'

Sydney Sweeney wasn't thinking ahead when she invited all of her family -- including her grandparents -- to the premiere of Euphoria Season 2.

The star sat down with Ellen DeGeneres on The Ellen Show on Thursday to celebrate some of her latest accomplishments. The two spoke about the actor's Cosmopolitan cover, followed by Euphoria, where she plays Cassie Howard.

"So for the premiere, I invited my entire family -- my grandparents, my uncle and so on. I was like, 'It's a Hollywood premiere, you gotta come!'" She continued: "We were all sitting next to each other in front of the giant screen. I was on the floor. I wasn't thinking! I was so excited." When asked how her grandparents reacted to nude scenes on the show, she responded: "They said I have the best tits in Hollywood." Sitting in the audience, Sweeney's grandma gave a thumbs up to show her support.
