Los Angeles: Actress Kristen Stewart is losing sleep over the fact that she has to promote her new movie "On The Road" at the Toronto Film Festival, starting 6 Sept.
"On The Road" will kick start the annual event Thursday night. "Kristen is worried because it opens the festival, a lot is expected of it and just prays that it's well received. She is trying to find some inner peace within herself," said a source.
Stewart, who had an affair with director Rupert Sanders behind beau Robert Pattinson's back, is nervous about her first red carpet appearance since her cheating scandal and hopes her personal life doesn't overshadow how the film is received by the critics, reports radaronline.com.
"Kristen Stewart hasn't been able to get a wink of sleep in the run-up to the film festival," a source revealed.
Even though members of the media have been strictly told that questions about her cheating scandal are off-limits, she's been fretting over the film's premiere," said a source.
"She really hopes that the critics are kind to her when it comes to the reviews and they don't judge her on her personal life," added the source.
"On the Road" is very close to Stewart's heart. She is a big fan of the original novel by Jack Kerouac and wants the movie to get the praise she thinks it deserves.
