Kristen Stewart's public apology for cheating on Robert Pattinson with director Rupert Sanders, hasn't done anything to help her relationship with the actor.

People magazine reports that Pattinson has packed his bags and moved out of the Los Angeles home he shares with Stewart.

Sources told Page Six that the 26-year-old "Twilight" star may have already known about Stewart's infidelity, as witnesses reportedly saw the couple fighting backstage at Sunday night's Teen Choice Awards, just days before the photos of what looks like Stewart and Sanders kissing were made public.

Pattinson is reportedly "heartbroken and humiliated" over Stewart's infidelity, which she claims was a "momentary indiscretion." Sources also told People the actor is "heartbroken and angry" and currently not in contact with his girlfriend of four years.

Many have questioned why Stewart would issue an apology at all, but if Pattinson isn't speaking to her, it may just have been a desperate attempt to reach out to him
