Christie Brinkley's Mom Says Peter's Cooked!

If the cheating S.O.B. who screwed up his marriage to Christie Brinkley is hoping for a reconciliation, he shouldn't hold his breath, says the supermodel's mom.

"She is not wavering ... or taking him back. She is not planning that. Not true," Marjorie Brinkley said.

As the New York Daily News revealed on Tuesday, the still-stunning model and mom filed a "summons with notice" against Peter Cook in Suffolk County Court in Riverhead, N.Y., preparing the legal grounds for a divorce.

However, Brinkley has yet to formally serve her philandering hubby with the summons, the crucial next step in beginning the divorce proceedings. The summons expires 120 days after the filing date.

Cook's lawyer has said the 47-year-old architect wants forgiveness and to put this behind him. But that's not happening, said Marjorie Brinkley, who says her 52-year-old daughter has already been asked out by several men.

At least for now, she's turned them down.

"I have no idea if she will date again," the elder Brinkley said. "Of course, I would like her to. I don't want her to be a recluse, which she would never be because she is too vibrant, too alive."

Christie Brinkley has not been spotted outside her $22 million Bridgehampton, N.Y., mansion since Monday, when she drove one of her children to a day camp in nearby Sag Harbor.

She has been generally gracious toward reporters in the days after Cook's affair with his 19-year-old assistant, Diana Bianchi, became front-page news. But the environmentally conscious cover girl appeared flustered by the presence of the media on Monday.

Cook and Brinkley have been speaking in the past few weeks, but those discussions have centered around their children.
