Sydney Sweeney, who plays Cassie Howard on the hit HBO series Euphoria, told Ellen DeGeneres that one of the most passionate supporters of her career is her grandma, even when watching explicit scenes she was in that most grandparents would shy away from ever mentioning.

Sweeney described her character of Cassie, as “a basket case. She doesn’t have it together.” Her character, who finds herself in a love triangle between two other main characters in season two, is featured in multiple sex scenes throughout the show. Sweeney told Ellen she “didn’t really think” about how much on-camera sex her family would be watching her have until after she invited them all, including uncles and grandparents, to the show’s Hollywood premiere.

The actor said she was quickly “on the floor,” from embarrassment as the screening began. Her family was still supportive, though, and according to Sweeney, her grandparents quipped, “I have the best t–ts in Hollywood.” Her grandma was even sitting in the Ellen audience and flashed the host a thumbs-up.

Sweeney has spoken in the past about filming nude scenes for Euphoria, and told Teen Vogue, “I think it’s important to the storyline and character. There’s a purpose to what the character is going through. That’s the character. We all get naked in real life. We show this character’s life and what they’re going through. Cassie’s body is a different form of communication for her.”

She has also praised the show’s creator, Sam Levinson, for letting her set her own boundaries while filming. “I’ve never felt like Sam has pushed it on me or was trying to get a nude scene on an HBO show,” she told The Independent. “When I didn’t want to do it, he didn’t make me.”
