After the photo scandal that revealed actress Kristen Stewart had a fling with the "Snow White and the Huntsman" director Rupert Sanders, speculations arise that she and boyfriend for four years Robert Pattinson will break up.

Twi-hards were devastated after hearing the news that Kristen Stewart cheated on the British actor during the filming of her most recent movie "Snow White and the Huntsman." It was revealed that aside from playing the "fairest of them all" princess, Kristen Stewart also played the role as Sanders' girlfriend for a brief time.

Us Weekly obtained scandalous photos of Stewart and Sanders that served as evidence of the fling going on between the two. Rupert Sanders is currently married to British Vogue model Liberty Ross, and the couple has two children.

22-year-old Kristen Stewart and director Rupert Sanders, 41, both released public apologies at the same time admitting the rumors.

"I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected. This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I'm so sorry," the actress told People.

"I am utterly distraught about the pain I have caused my family ... My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying that we can get through this together," Sanders also told People in a separate statement.

The scandal led fans to gossip if the Twilight sweethearts will head to split. Angered fans of RPatz and Robsten took Twitter to lash out on the actress calling her names such as "home wrecker."

The scandal is off timing as the Kristen and Rob are busy promoting the final film of The Twilight Saga, which will hit the theaters in November. There is no denying it that their real life romance has been a plus point in promoting the Twilight films. Will the crack in their relationship affect the promotion of their latest film?

The two appeared at the recently concluded Teen Choice Awards and Comic Con event looking sweet and so much in love.

In a recent interview with Blackbook magazine, Robert Pattinson cleared the rumors that he and Kristen will not get married this year. Not yet. But the actor implied that it will happen. Will he stay true to his words?
