The 22 year old admitted to romancing her married Snow White and the Huntsman director Rupert Sanders in July (12), and the confession ended her relationship with longtime boyfriend Robert Pattinson.
The couple recently reconciled and now Bewley and Cudmore, who play vampires Demetri and Felix in four of the franchise's films, insist they don't view Stewart any differently because she made a romantic mistake.
Cudmore tells HollywoodLife.com, "Think of how many mistakes you made at 22 years old. Like, I made a million. The problem is we're in the spotlight, but, whatever. It's a relationship, and people go through ups and downs and they have their problems."
And Bewley agrees, confessing he's cheated once or twice before: "Honestly, I used to cheat so much it would be very hypocritical of me to pass judgment on Kristen. I know what it's like to have an inflated libido. Probably why I'm not in a relationship right now."
