Kristen Stewart may have a chance to get her Edward Cullen back.

Stewart mad a shocking mistake by having a "momentary indiscretion" affair with "Snow White and the Huntsman" director Rupert Sanders back in July, which left boyfriend Robert Pattinson extremely hurt and disappointed.

It was revealed Tuesday that after a long, emotional phone call between the two, Pattinson, 26, agreed to meet with Stewart, but he had some ground rules if they wanted the relationship to work.

Now, Stewart is trying her best to see what she can do to get him back.

According to Times Live, the 22-year-old "Twilight" actress is determined to rekindle her relationship with Pattinson, and is turning to her "On the Road" co-star Tom Sturridge, who has known Pattinson for years, to help her.

A friend told HollywoodLife.com, "Kristen is really stressed out and nervous about making her first public appearance at the upcoming Toronto Film Festival. But it's not the premiere that she is worried about, it's her pending conversation [with Sturridge].

"She wants to have a private conversation with Tom and try and convince him how sorry she is and how she wants Rob back. She is more concerned with her conversation with Tom than with the premiere of On The Road. The only thing that matters to her right now is getting Rob back and she knows the way to get to Rob is through his best friends."

Stewart is also reportedly planning to ask Sturridge's fiancée Sienna Miller for advice and wants to assure the couple she will never hurt Pattinson again.

The insider added, "She wants both Tom and Sienna to know that she never meant to hurt Rob and that she is not an evil person.

"She is hoping and praying that Tom and Sienna will understand and forgive her. And that they will help her win Rob back!"

It was reported earlier that, According to Us magazine, friends of the 26-year-old actor, including Sienna Miller and Tom Sturridge, have been "begging Rob to end it for good," said a source close to Pattinson.

Entertainment Wise reported earlier in August that Sturridge, who co-stars in the movie "On the Road" with Stewart, his reaction at the London premiere (which Stewart didn't attend) to the mention of her named seems that the subject isn't something he's happy about.

"Speaking to Entertainmentwise at the premiere in London last night Tom couldn't hide his disdain, visibly flinched and looking uncomfortable when asked about his co-star and seemed awkward when asked if it was nice to "work with a friend" on the movie," the report said.

The actor didn't mince his words over the scandal later on the red carpet and snapped at a journalist who asked him about the cheating revelations.

"I don't talk about my friends behind their back," he snapped according to The Mirror.

Good choice, Sturridge.
