Robert Pattinson's sisters do not want him to reunite with his cheating ex-girlfriend.
Lizzy and Victoria Pattinson have told their little bro, "Don't even think about getting back together with Kristen Stewart," according to a report by Radar Online.
"Robert's sisters were fuming with Kristen for hurting their brother in the way she did," a source told the site.
"It's a case of once she's cheated, what's to stop her doing it again? And Lizzy and Victoria are pretty unforgiving over Kristen's actions."
"They will kill him if he gets back with Kristen," the source added.
Kristen isn't faring well since the split, with reports she's suffering from insomnia in the lead up to the premiere of her new film On The Road at the Toronto Film Festival.
"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."
In her first magazine interview since the split, Kristen complains about the pressures of fame.
"People expect it to be easy because there you are, out there, doing the thing that you want and making lots of money out of it," the actress tells British Vogue.
"But, you know, I'm not that smooth. I can get clumsy around certain people. Like if I were to sit down and think, 'OK, I'm really famous, how am I going to conduct myself in public?' I wouldn't know who that person would be! It would be a lot easier if I could, but I can't."
