After losing long-time boyfriend Robert Pattinson due to her foolish fling with Snow White and the Huntsman director Rupert Sanders, now Kristen Stewart is ready to do anything to win her ex-flame back. According to sources, Kristen is planning to ask Roberts best friend Tom Sturridge to help her win Roberts love and faith back. A friend of the actress 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 her On The Road co-star Tom 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,'' the friend added.
