'Kristen is acting like a heartbroken teenager,' a source told. 'She is crying her eyes out non-stop and does not want to communicate with anyone.'
According to insiders, Kristin is terrified that she has lost Rob forever, and that there is no going back for the pair, following her affair with the Snow White And The Huntsman director.'She is beyond mortified and humiliated and she is also broken hearted,' the source said.
It seems that the consequences of Kristen Stewart's actions are continuing to sink in... and hard.
After moving out of the Los Angeles home she shares with boyfriend Robert Pattinson following the expose of her steamy affair with married director Rupert Sanders, the Twilight star is said to be in pieces.
The 22-year-old is reportedly staying with her former producer Giovanni Agnelli at his Sunset Plaza abode.
The Welcome To The Rileys movie maker offered the actress a place to stay after she moved her belongings out of her and Robert's Hollywood Hills home last week.
Holed up in his home and terrified to face the pubic, the actress is said to be beside herself.
'She says she truly loved Rob. She says he was her soul mate, but she blew it and now she is scared that she has lost him forever.
'She is pretty much inconsolable.'
The devastated star is said to be so upset that she has not showered in several days and is gorging on ice-cream.
'Kristen hasn't showered or changed or washed her hair in several days,' the source told Radaronline.
'She is laying around in her T-shirt and shorts and eating ice cream. She really wants to believe that she can win back Rob, but I think deep down she knows that isn't the case.'
