Kristen Stewart ‘Begs Robert Pattinson’s Best Friend Tom Sturridge For Help To Win Him Back’ Kristen Stewart has reportedly turned to Robert Pattinson’s best friend and her ‘On The Road’ co-star Tom Sturridge to help convince the ‘Twilight’ hunk to take her back following her affair with director Rupert Sanders.The 22 year-old is said to be desperate to get her boyfriend of three years back, but after humiliating him so publicly she is said to have turned to his friends to try and convince them she is the best person for him to be with and will try to win Tom round at the Toronto Film Festival in September.It will be Kristen’s first public appearance since the scandal broke and while she is nervous, she is hoping it will be a good place to speak to Tom.“Kristen is really stressed out and nervous about making her first public appearance at the upcoming Toronto Film Festival,” a source told HollywoodLife.“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.”They went on:“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.”Kristen thinks that Tom’s fiancé, Sienna Miller maybe some one she can speak to about the scandal. Sienna, who recently gave birth to her first baby with Tom, famously took back Jude Law after he cheated on her and was also caught up in a scandal herself when she had an affair with married actor Balthazar Getty.The source explained: “[Kristen] 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 Rib back!”We’re not sure how well that will go down, after all Jude and Sienna eventually broke up and the actress is a lot older and wiser now.Even if Kristen does manage to convince the couple, Rob is said to be determined to move on and has been spotted partying with close friend Katy Perry as he gets his life back in order.We’re not sure how well the conversation will go between Tom and Kristen. When Entertainmentwise spoke to the actor at the premiere of ‘On The Road’ in London, he seemed to visibly grimace when we mentioned the actress and was reluctant to talk about her.
