Kristen Stewart with 'Twilight' co-star Taylor Lautner

The 22-year-old actress' relationship with Robert Pattinson, 26, has been strained ever since her infidelity with married director Rupert Sanders was discovered last year and Kristen is hoping their friend and 'Twilight Saga' co-star Taylor, 21, can help.

A source told RadarOnline: “Kristen has been spending a lot of time with Taylor of late because she’s been using him as a sounding board for her relationship with Robert.

“She thinks that he may have some insight in how she should proceed with Robert – and where their relationship is going.

“Robert and Taylor are also tight, so she’s been fishing a little to find out if they have been talking about anything.

“But Taylor has just told Kristen that she has to give Robert time to heal still. It’s not even been a year since the now infamous cheating scandal, so he can’t be expected to forgive and forget so quickly.”

Robert is currently filming 'The Rover' in Australia and while he doesn't want Kristen to visit him on set, Taylor has cautioned her to be patient.

The insider added: “He also told her that Robert is busy working and trying to stay together long-distance is as tough as it gets. She needs to just be patient until he comes back.”
