Robert Pattinson's sisters won't be happy if the actor gets back to ex-girlfriend Kristen Stewartwho cheated on him with director Rupert Sanders.
Both Lizzy and Victoria Pattinson have warned their brother of the old adage, "once a cheater, always a cheater" telling him he would be foolish to let Stewart back into his life, reports radaronline.com.
"Robert's sisters were fuming with Kristen for hurting their brother in the way she did," said a source.
"Lizzy and Victoria feel terrible for heartbroken Robert, especially because of the embarrassment that was caused by the manner in which the affair was exposed. They've told him that there's no way he can take Kristen back after what she did to him. They will kill him if he gets back with Kristen," the source added.
