We've got brand new details about the torrid fling between Kristen Stewart and married movie director Rupert Sanders, which threatens one of young Hollywood's most glamorous relationships, the actresses' three-year romance with Twilight co-star Robert Pattinson.
A published report claims the 22-year-old actress and the 41-year-old Snow White and the Huntsman director indulged themselves as they traveled around Los Angeles July 17. Witnesses say they were hardly able to keep their hands off one another, and a series of photos confirms such, showing the director and actress in a number of romantic embraces -- or compromising positions, depending on how you look at it.
"He was all over her," said one photographer who witnessed the hijinks, while another said Kristen and "would only take a break from kissing when they thought someone was walking by.
"It seemed like they couldn't get enough."
One photog followed the A-list beauty from her Los Feliz home around the City of Angels, thinking it odd when she parked her swank black Mini Cooper in the lot of a deserted building, only to see Sanders pull up and passions ignite yet again.
"Kristen was sitting up with her back against the driver's-side window, and this guy was kissing her entire body," the witness said. After the director sensed they were being watched, "They left."
The pair then traveled to an area in L.A. called the Pacific View Trail, which is adjacent to the Hollywood sign. Kristen parked the car strategically, with Rupert's instructions, and the making out commenced yet again.
