The tumultuous Robert Pattinson/Kristen Stewart romance might harm "Breaking Dawn Part 2," says the pair's co-star Ashley Greene.

"I don't know. Hopefully, it won't taint it and people will still be able to enjoy the movie," Greene said in an interview with Seventeen magazine. "I think a lot of people see us as our characters; I really want them to still be able to do that."

I don't know either. Stewart cheating on Pattinson with director Rupert Sanders has me thinking I may only see it nine times instead of 11 or 12.

Greene says she knows what it's like to be in love and would never wish anything but happiness for her co-stars and friends, who made her time on set memorable.

"We secretly coordinated a dance-off during a scene! We were all in on it, but (director) Bill Condon didn't know," Greene explained of one of her last days shooting the franchise. "(All the vampires) were supposed to charge at each other and destroy each other, but instead we just started dancing! Everyone did it -- the Cullen clan and probably 20 vampire extras! It was such an amazing way to end it all."
