Kristen Stewart has been subjected to speculation that she is again seeing Rupert Sanders, the man she cheated on Robert Pattinson with last year, after she was photographed with a companion resembling her former lover.

The On The Road actress, who is believed to have reconciled with Pattinson and was pictured hand-in-hand with her Twilight co-star at Coachella less than two weeks ago, was spotted getting into a car with a man many have alleged is Sanders.

The photos, taken in Silver Lake, California on Sunday (April 21) after Stewart had been dining out with friends, see Stewart climbing into the passenger seat of a black Acura vehicle similar to one claimed to be owned by Sanders.

However, others have suggested that the man in the car is a valet driver, as in some pictures Stewart appears to be waiting at a valet stand outside the Malo Tanquira restaurant.

Pattinson is believed to have jetted out of Los Angeles on the same night the photos were taken.

Stewart admitted her affair with her Snow White and the Huntsman director Sanders last July.

The revelation led to Stewart and Pattinson separating, and the status of their relationship has been unclear ever since.

Meanwhile, Liberty Ross, Sanders's wife of ten years and mother of his two children, filed for divorce from the director in January.

A representative for Stewart has yet to comment.
