The 22-year-old star – who recently made a public apology to boyfriend Robert Pattinson for cheating on him with her 'Snow White and the Huntsman' director – is being supported by her 'Panic Room' co-star after the 49-year-old actress reached out to her young friend.
A source said: "As soon as she heard the news, Jodie contacted Kristen to offer her support. They have been close friends since they starred opposite each other in the 2002 movie 'Panic Room', and Jodie is a mother-like figure to her.
"Jodie told Kristen to take no notice of the media bashing and said if she wanted to cry her heart out to her she's always available. Jodie loved Rob and is disappointed with Kristen for cheating on him. However, she knows at 22, she's still very young and unfortunately people make mistakes in life. She thinks Kristen will learn from this and will only grow into a more mature person because of it."
However, not all is easy for Kristen, as she is still fighting with British-born Robert about who should look after their dog Bear.
The source added to RadarOnline.com: "After Rob moved his things out of their Los Angeles home, he then told Kristen he wanted Bear. She was heartbroken; they adopted Bear together and she always felt that he was their little baby.
"But Rob was so hurt by Kristen's actions he decided that he wants the dog to help him get over what happened. After all, a dog is a man's best friend and Bear is such a good companion. However, Kristen won't give up Bear in a hurry."
Robert is believed to be hiding out in Reese Witherspoon's holiday home in California while he decides what to do with his future.
