Robert Pattinson`s sisters hate Kristen Stewart

Los Angeles: Robert Pattinson`s sisters won`t be happy if the actor gets back to ex-girlfriend Kristen Stewart who 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 a website. "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. IANS
