Most of the time, Sydney Sweeney really has to focus and get into character on Euphoria, but while filming the latest episode, the blonde beauty got to show a different side to Cassie.

In season 2, episode 4, Cassie uses Maddy’s (Alexa Demie) birthday party as an excuse to try and seduce Nate (Jacob Elordi).

“It was a lot of fun. I was enjoying that because I finally got to let loose as Cassie and … it was cool. And I actually got very tangled [in the balloons]. To the point that they had to call cut because it was all around my neck,” Sweeney said of her character pulling out all of the stops to impress the handsome hunk.

Unfortunately, things backfire, as Cassie ends up puking in a hot tub.

“During the hot tub scene, during the throwing up, I got really grossed out,” she said of the pivotal scene. “They had this invisible tube that looked like a horse bit and they put it in my mouth and I had to somehow hold and make it look semi-normal and then throw up over everyone which was … it was so gross.”

“That episode is so chaotic for [Cassie],” Sweeney added. “What I love about [creator] Sam [Levinson] is every shot he wanted her to be drinking a different bottle. So if you notice, every single shot she has a completely different bottle in her hands. By the end of that episode I’m like, how many drinks is she in? She was gone.”

Despite playing a hot mess, Maude Apatow had nothing good things to say about Sweeney’s performance. “Sydney was so good, the dancing with the balloons,” Apatow recalled. “We were all gathered around the monitor watching her, like dying. She’s so good.”

Nonetheless, The White Lotus alum loves when she gets to film alongside the other ladies. “But I always love these kinds of scenes where we’re all together because a lot of times we don’t get to have many scenes where we have a bunch of girls together and we were literally in one room. So, it was chaotic but fun,” she stated.
