News broke earlier this week that "Twilight" actress Kristen Stewart cheated on her co-star and boyfriend Robert Pattinson with Rupert Sanders, the 41-year-old married director of "Snow White and the Huntsman."  Since photos were leaked by Us Weekly, we have learned of new developments in their cheating scandal.

Despite Stewart's public apology on Wednesday, Pattinson has moved out of their Los Angeles love nest. Sources revealed to the Huffington Post that the "Twilight" and "Water For Elephants" heartthrob is "heartbroken and humiliated" by Stewart's infidelity.

To further fuel Pattinson's heartbreak, new pictures show that Stewart wore a hat from Pattinson while while having her steamy rendezvous with Sanders. Stewart and Pattinson were together for four years.

Besides the July 17 photos that show Stewart and Sanders in an intimate embrace and hot hookup in the car, Us Weekly also features a photo that delivers a slap in the face to Pattinson. Stewart was caught driving Sanders around that day wearing her boyfriend's beloved LA Dodgers hat.

Us Weekly reports that the "LA Dodger" photo in question depicts the pair "scoping out secluded places to make out."

Stewart, 22, had used the hat in an attempt "to go incognito." The plan was obviously unsuccessful.

According to the magazine, this isn't the first time that the actress has borrowed one of her boyfriend's hats in an attempt to blend in to the crowd. Stewart in April was spotted wearing Pattinson's Baltimore Orioles hat at the Coachella Music Festival.

During their highly publicized July 17 tryst, Sanders only donned sunglasses to help disguise himself.

The pair reportedly "seemed like they couldn't get enough," according to some reports, with a photographer reportedly saying it looked like Stewart and Sanders were having a marathon makeout session.

Friends of the starlet said Stewart knew "it was a mistake and a complete lapse in judgment."

Since the steamy photos surfaced, more photos of the the actress with the married director have come to light. A couple pictures circulating the web show the pair on a cozy dinner date.

Sanders, who has two young children with wife, Liberty Ross, has since issued a statement of apology as well. Besides revealing how distraught he was over the pain the affair has caused his family, he explained that "I am praying that we can get through this together."
