In the wake of girlfriend Kristen Stewart's cheating scandal, Robert Pattinson has decided he's not ready to face the press.

According to Entertainment Tonight, Pattinson, 26, has canceled an upcoming press appearance in the U.S. for his new film Cosmopolis. The film is set to premiere soon in NYC, but it is unknown if Pattinson will be in attendance. 

However, a rep for the actor has since told Gossip Cop, "No confirmed engagements have been canceled. Any reports to the contrary are inaccurate."

The actor's Twilight costar and longtime love Stewart, 22, was caught cheating with her Snow White and the Huntsman director Rupert Sanders, 41, on July 17. As exclusive photos in Us Weekly revealed last week, the actress and Sanders, who has two young children with British Vogue model Liberty Ross, had a marathon makeout session in Los Angeles.

Reports Tuesday claimed Pattinson has been easing his pain after the scandal by partying with friends in his hometown of London. But sources told Us, the story wasn't true. Instead, Pattinson has been hiding out since the news broke late Tuesday and sources close to the actor tell Us he is "really depressed."

"Rob is beyond devastated," a source explained. "He's so heartbroken. He's shocked she could hurt him and humiliate him this way."

Stewart publicly acknowledge her love for Pattinson in an apology statement on July 25. "I'm deeply sorry for the hurt and embarrassment I've caused to those close to me and everyone this has affected," the actress said. "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."

While Pattinson continues to stay out of the spotlight, Sanders stepped out Monday to face the paparazzi. The English director wore his wedding ring and a somber look on his face while out and about in Los Angeles. Sanders also made a public apology to his wife in a statement to Us last week. "I am utterly distraught about the pain I have caused my family," he said. "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."
