Mopey KRISTEN STEWART gets down and dirty with her much-older married SNOW WHITE movie director!

Multiple reports claims actress Stewart, 22, and director Rupert Sanders, 41, who teamed on the Snow White and the Huntsman more than indulged themsleves 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 steamy photos confirms such, showing the director and actress in a number of romantic embraces — or compromising positions, depending on your jaded point of view.

“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 El Lay, and when Stewart parked her black Mini Cooper in the lot of a deserted building, Sanders pulled and they began swappping spit 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.”

Later on, Kristen and Rupert got back in the car when some passerby dog walkers ambled through; witnesses say they spent another 20 minutes kissing, before she dropped him off three blocks away from his home. They kissed one more time, and then the Snow White and the Huntsman director walked home, RadarOnline.com reported.

K. Stew’s relationship with so-called Twilight beau Robert Pattinson has fueled career buzz, while Sanders, 41, is married to British Vogue beauty Liberty Ross, 33. The couple have two kids, ages 7 and 5.

LATEST: Stewart issued a statement and apologized via her PR flack,  “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.” 

Stewart and Sanders will begin shooting the sequel to their Snow White flick shortly.
