The photos of Stewart, 29, and Sanders, 48 caused a stir when they were published in US gossip magazine Us Weekly as the actress was in a relationship with her Twilight co-star Robert Pattinson at the time.
Sanders was also married to model Liberty Ross, who then divorced her husband the following year.
Stewart issued a public apology shortly after the pictures became public, saying she was “sorry for the hurt and embarrassment I’ve caused” and revealing that “this momentary indiscretion” had “jeopardised the most important thing in her life,” her relationship with Pattinson.
He went on to direct the 2016 sequel The Huntsman: Winter’s War, which featured original star Charlize Theron alongside Emily Blunt and Jessica Chastain but snubbed Stewart.
Addressing the scandal in an interview with SiriusXM radio host Howard Stern, Stewart said: “We lived in a different time then, you know what I mean? I feel like the slut-shaming that went down was so absurd.
“And they should’ve put me in that movie! It would’ve been better. Not to be a d***, but…”
“They didn’t put me in that movie because I went through such a highly publicised scandal, and so they were like scared of touching that.”
She went on to say that she could have been included in a “great” sequel in “a functional and healthy way,” adding: “That was a really hard period of my life, I was really young, I didn’t really know how to deal with that. I made some mistakes. And honestly, it’s no one’s business.
“Basically what I’m saying is, the work to me genuinely was ignored in a really sort of frivolous, silly, petty way. For a group of adult people who were supposed to be running studios and making films? Honestly, the film industry in Hollywood is so fear-based.
“I think they’re idiots, because if you take a little risk and make something good, people will watch it and like it and pay you.”
Stewart’s next major role will see her star alongside Naomi Scott and Ella Balinska in the Charlie’s Angels reboot, which arrives in cinemas on November 29.
