The flip was just about to be switched on the promotional machine behind the "Twilight" movies when the bombshell hit that one-half of its onscreen couple, Kristen Stewart, had cheated on the other, Robert Pattinson, in real life.

The final installment in the massively successful series -- the previous installment made $380 million alone -- is slated to open worldwide in November, which means Pattinson, Stewart and its other stars are scheduled to start promoting the series in September, which is now just a few short weeks away.

But at least one star, Christian Serratos, who has played a pal of Stewart's character Bella in all five of the "Twilight" films, says Stewart's admission that she slept with the director of her last film wouldn't mean a thing to "Twilight" fans.

"Of course people are fans of us now, but I think above anything, they're fans of these characters," she told Us Weekly on Tuesday. "I don't think anyone's really gonna give a s**t. They're gonna see the movie; it's going to be awesome."
