New photos of the two kissing have been released.
Us Weekly, which had caught the two in a “steamy rendezvous” on July 17 in Los Angeles, has posted more photos on its website.
The photographer claims he followed the Twilight star as she left the house she shared with Robert Pattinson in her Mini-Cooper.
After she got a call on her cell phone on the way back from the gym, she parked and waited for the Snow White director.
They then started driving around Los Angeles, looking for places to make out.
“Kristen was sitting with her back up against that driver’s-side window, and this guy was kissing her entire body,” the photographer tells Us Weekly.
The magazine writes that Stewart and Sanders were “kissing like crazy.”
“Kristen was sitting with her back up against that driver’s-side window, and this guy was kissing her entire body,” a witness said.
Later, the pair drove to a secluded area near the Hollywood sign.
“He seemed more cautious,” the witness adds. “She was lost in the moment. It was clearly all she was thinking about.”
Following the unfolding of their fling, both Stewart and Sanders issued apologies.
Stewart was quick to express her regret: “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.”
“I am utterly distraught about the pain I have caused my family,” Sanders, a 41-year-old married man and father of two, said in a statement. “My beautiful wife and heavenly children are all I have in this world. I love them with all my heart. I am praying we can get through this together.”
