Kristen Stewart reportedly is hiding in her producer pal's house. The actress has reportedly moved out of the house she shared with boyfriend Robert Pattinson following the revelation of her affair with director Rupert Sanders.

Radar Online is reporting that Stewart has been staying with Giovanni Agnelli who produced her film "Welcome to the Rileys". A source told the site, "Kristen is acting like a heartbroken teenager. She is crying her eyes out non-stop and does not want to communicate with anyone."

"She is beyond mortified and humiliated and she is also broken hearted," the source added. "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."

Agnelli, whose house is located in the trendy Sunset Plaza area, is the same person who defended Stewart via Twitter last week. He said Stewart is like a sister for him, adding she did not have any sexual relationship with Sanders.

During her grief of losing Pattinson, Stewart reportedly "hasn't showered or changed or washed her hair in several days".

Pattinson has also found a sanctuary away from the media. He is staying at "Water for Elephants" co-star Reese Witherspoon's vacation home in Ojai, California.
