Kristen Stewart is going to the "On the Road" premiere, but she's definitely nervous about it.

Stewart put herself in a really bad position when it was revealed in July that she cheated on boyfriend Robert Pattinson with "Snow White and the Huntsman" director Rupert Sanders.

She is reportedly worried and nervous about her first public appearance, but is more nervous about her pending conversation with "On the Road" co-star Tom Sturridge.

According to Entertainment Wise, a source told Hollywood Life,"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 her 'On The Road' co-star Tom Sturridge."

Her plan on getting back Pattinson, 26, was revealed earlier this week.

It was revealed Tuesday that after a long, emotional phone call between the two, Pattinson 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!"
