Remember when Kristen Stewart cheated on Robert Pattinson with her married director, Rupert Sanders? Well, according to Stevie Nicks, you shouldn't. You should forget all about it and stop being such a jerk.

Nicks is a pretty big Twi-hard herself, and she rushed to the defense of K-Stew when asked about her affair.

"I was her age once, and exactly what happened to her happened to me two or three times, and whoever it was that I was with forgave me all two or three times," Nicks told Us Weekly.

Thing is, when you're Stevie Nicks in the 70s, whoever you're with is totally going to forgive you, because you're rich, gorgeous, at your prime and possibly on a dangerous drug-fueled bender.

She added, "The fact is that when you're young and you've been in a relationship for a long time and something comes along that is a little bit overwhelming and magical, and you're kind of in another situation with someone else ... Things happen."

"I really always want to say to people, 'People who live in glass houses shouldn't throw stones.' It's not anything the rest of us haven't done." The fact that Nicks assumes infidelity is so common is scarier than any glittery vampire we can imagine, but fair enough.

She offered her blessing to the couple: "If what they have is that special they can overcome it, then good for [them]."

And good for the franchise. But we're sure that's totes a coincidence.
