The Snow White and the Huntsman actress is said to have reached out to the director following her second split from Robert Pattinson.
Robert Pattinson and Kristen Stewart's relationship was recently reported to have ended once again.
The Twilight co-stars originally split up last summer when Stewart admitted to cheating on Pattinson with the married director Sanders.
"Kristen was feeling low - the lowest she's ever felt - when Rob flew to Australia... so when he left, she reached out to Rupert to see if he was okay and suggested meeting for a coffee," a source told Heat.
However, Sanders reportedly refused her offer of a meet-up, with Pattinson also finding out himself through a mutual friend.
She allegedly contacted Sanders two weeks ago in order to "talk to someone who was going through the same thing".
Rupert Sanders is currently going through a divorce from his wife of ten years Liberty Ross.
Stewart and Pattinson reconciled in September, but were later rumoured to have been "fighting a lot", with Pattinson said to be feeling "unhappy" in the relationship.
