Jodie Foster is being "an incredible friend" to Kristen Stewart in the wake of the star's infidelity scandal.

The Twilight actress issued a public apology to her estranged boyfriend Robert Pattinson for cheating on him with Rupert Sanders.

Kristen went into hiding for several weeks following the shocking revelation.

The actress emerged into the public eye for the first time this week and sources credit Kristen's move to Jodie's support.

"Jodie has been an incredible friend to Kristen through this whole situation," an insider told Radar Online.

"She told Kristen that it was no good moping around the house and that the sooner she faced the world and was seen in public, the quicker she can move on with her life."

Jodie has been consoling Kristen since the onset of the scandal.

"As soon as she heard the news, Jodie contacted Kristen to offer her support," the source continued.

"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."
