Montag, Pratt siblings 'clueless on divorce'

Holly Montag and Stephanie Pratt have said that they are unsure whether Heidi Montag and Spencer Pratt are really getting divorced.

The Hills co-stars were quizzed about the couple's relationship during an appearance on yesterday's The Hills: A Hollywood Ending to mark the series finale of the show.

"I really don't know. I obviously have no frame of reference on the situation. I would have to say by past history I would assume not but I don't know," said Montag, who is Heidi's sister.

"I just remember then being so happy and so in love," added Spencer's sibling Stephanie. "I could never see this coming. I haven't talked to them since September. They are strangers to me. I'm clueless."

The presenter then told Montag - who became tearful after watching a montage of Heidi's time on the show - that he had faith they would resolve any differences.

"Me too," she replied. "I have all the faith in the world in my sister. She is the best person."
