Kristen Stewart's affair scandal happened at a very bad time for the "Twilight" movie franchise. The series' final installment, "Breaking Dawn: Part 2" is set for release in just three months, and its massive promotional push is being hammered out as we speak.

Experts we spoke to said Stewart's affair with the married director of her last film, and its subsequent ramifications on her long-term relationship with "Twilight" co-star Robert Pattinson, could cause big problems in the run-up to the "Twilight" finale.

"I would expect the press schedule to be altered significantly as a result of the recent developments. From the very beginning, neither Stewart nor Pattinson ever seemed especially comfortable doing press but have gradually appeared to find their comfort zones. Yet the scandal is almost certainly going to have them shying away from the direct glare of the media," entertainment reporter Scott Huver told FOX411's Pop Tarts column.
