Kristen Stewart's costars have defended her affair with Rupert Sanders.

The 22-year-old actress - who had a "momentary indiscretion" with her 'Snow White and the Huntsman' director in August and recently reconciled with her 26-year-old long-term boyfriend Robert Pattinson - is entitled to make mistakes according to her 'Twilight Saga' costars who say they don't judge her.

Daniel Cudmore, 31, who plays Felix in 'Breaking Dawn: Part 2' said: "You know what: I think it's ridiculous that people talk about people's lives, yet we're in an industry where their lives, our lives, are out in the public. I mean, 22 years old. 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."

British actor Charlie Bewley, 31, who plays Demetri in the hit movies also admitted he doesn't judge the actress because he has made the same mistake himself.

He said: "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. Probably why I'm not in a relationship right now."

Kristen and Robert's relationship is now said to be back in a "magical place" and although the couple haven't moved back in together they are spending as much time together as possible.

The couple attended Maroon 5's Halloween bash at the Hollywood Forever Cemetery last night (31.10.12) and were spotted holding hands.
