'Euphoria' actress Barbie Ferreira left HBO show 'to not be the fat best friend'

Euphoria fans upset with Katherine "Kat" Hernandez's storyline in Season 2 weren't alone, as the actress who played her was also disappointed with the character's trajectory.

Barbie Ferreira finally explained in-depth the "mutual decision" for her to leave the hit HBO television series during a podcast episode of Armchair Expert with Dax Shepard.

"I think my character who I love so dearly, I don't think there was a place for her to go," the actress said.

Although Barbie thought Kat didn't necessarily run her course yet with more directions to head to, she believed it wouldn't have fit into the show.

"I don't know if it was going to do her justice and I think both parties knew that. I really wanted to be able to not be the fat best friend, you know. I don't want to play that and I think they didn't want that either," she said about leaving.

Barbie said that otherwise, she would have kept portraying Kat for as long as she was asked if they didn't decide to finish her run. Nonetheless, she said the role will stick with her forever.

"It obviously hurts because I love Kat and she was so important to me and I think to a lot of people, with all her good and bad mostly bad, which I love. And it was like a character I've never seen on TV before and I don't know if we'll ever get something like that in that specific way. That was so edgy," the Euphoria star reflected.

The Emmy-winning Euphoria (with back-to-back Best Actress Zendaya) features high school students who deal with adult issues afflicting teenagers like drugs, sex, social media, trauma, violence, and more.

While Kat was technically a main character in both seasons of the show, she was relegated to a less prominent role in the second season.

During the first season, Kat lost her virginity at a party only for her sex video (taken without her knowledge and consent) to be leaked for all her classmates to see. She spends her school year trying to change her reputation by changing her look and earning as a "cam girl."

In the second and latest season, she fakes a "terminal brain disorder" to manipulate her boyfriend into breaking up with her.

Generally, she is just seen making remarks from the side in reaction to her friends, including "Cass, that's like really bad" and "Maddy, no!"
