Warning: Spoilers ahead. If you have not watched ‘Euphoria’ Season 3, please do not proceed.
Sydney Sweeney left little to the imagination throughout the three seasons of “Euphoria,” which included several adult scenes, especially since season 3 followed her story as an up-and-coming OnlyFans model.
The actress who plays Cassie has been a key member of the cast alongside Zendaya and Jacob Elordi since the first season of the Sam Levinson-produced HBO series, which premiered in 2019.
Viewers watched her character ride the merry-go-round and get off in Season 1, and things got hot and heavy with Elordi’s character, Nate, in Season 2.
During an appearance on The Tonight Show Starring Jimmy Fallon in June 2025, Sweeney teased that Cassie would be leaning toward her “crazy” tendencies in Season 3, but this time it would be “even worse.”
“It’s so nice to be able to go back to Cassie and grow with her and get even crazier,” Sweeney told GQ in November 2025. “Roller coasters are so much fun to ride because you get to go to all these crazy places.”
That’s been true as fans have watched Cassie launch her career as an adult entertainer in the latest season, resulting in highs and lows for the character.
Page Six breaks down all of Sweeney’s sexiest moments from “Euphoria” below.
Kathy and Chris McKay Hookup (Season 1, Episode 1)
Sweeney kicked off the Emmy-winning series’ first episode with Cassie wearing nothing while getting intimate with her then-boyfriend Chris McKay, played by Algee Smith.
However, the racy scene quickly came to a halt when McKay strangled Cassie without her consent.
Sweeney’s character was taken aback by this situation and immediately told her lover to never do anything like that again.
Cassie and the Carousel (Season 1, Episode 4)
After taking MDMA at a carnival, Cassie jumps on a merry-go-round with fellow high school student Daniel DiMarco, played by Keian Johnson, during a fight with McKay.
While under the influence, she became aroused by the movements of the vehicle and climaxed in front of a large crowd of onlookers.
When Cassie finished speaking, she looked around in horror at what had just happened.
Kathy and Nate Bathroom Scene (Season 2, Episode 1)
Cassie started Season 2 with a heated and intense flirting session with her new boyfriend, Nate, played by Elordi.
In the scene, Cassie’s dress is pulled down as she and Nate get intimate in the bathroom.
Eventually, their relationship is interrupted when Cassie’s best friend and Nate’s ex-girlfriend Maddie, played by Alexa Demme, knocks on the door, unaware of their relationship.
Nate’s Fantasy Cassie (Season 2, Episode 2)
Cassie was naked again when Elordi’s character had an explicit fantasy about her.
At the time, Nate got into a bloody fight with Fezco, played by the late actor Angus Cloud, and was taken unconscious to hospital.
The two were also seen having sex, and Sweeney was later shown lying on a bearskin rug without any clothes on.
Cassie’s OnlyFans Career Takes Off (Season 3, Episode 2)
Kathy realized she couldn’t afford to buy Nate $60,000 worth of flowers, so she turned to OnlyFans to help pay for the wedding.
Throughout the episode, viewers watched her pose topless and wear various outfits, including a baseball cap and baby clothes.
Additionally, she wore an American flag while the housekeeper took photos of her.
Cassie Gira (Season 3, Episode 5)
Cassie’s most memorable look on the show was the leopard-print jumpsuit and matching gloves she wore during her dreams of fame as an OnlyFans model.
In the dream, Cassie grew into a Godzilla-like monster, towering over the city, walking toward a building with a man inside, pleasuring himself while watching videos of her on the computer.
As Cassie approached the man through the window, she popped out of her bodysuit, exposing herself.
Elsewhere in the episode, she wore a barely-there leotard while jumping rope for her subscribers, and later sucked her toes while recording content.
Kathy Nude and Python (Season 3, Episode 6)
In another risqué episode, Cassie was spotted without clothes wearing a yellow python for a photo shoot.
She was clearly struggling as the snake wrapped itself around her.
Sweeney’s character later changed into a pink lingerie set while posing with Anna Van Patten and Rosalia’s characters, Kitty and Magic.
Cassie’s Sexy Relationship with a Movie Star (Season 3, Episode 7)
Cassie’s coming-of-age scenes with movie star Dylan Reed, played by Homer Gere, son of Richard Gere and Carey Lowell, were another wild storyline this season.
The episode saw Cassie go after the actor in an attempt to get her followers back after impulsively deleting her OnlyFans account.
She strips naked for a wild sex scene that causes them to break up the bed.
After the conversation ended, Cassie grabbed Dylan’s phone and shared a video of them in bed, captioning it: “Best fucker in the world @itsjustmecassie.” The post went viral overnight.
