Peter Cook's ex-wife apologizes to Christie Brinkley for affair

The second ex-wife of Peter Cook has issued a written apology to his first wife — supermodel Christie Brinkley— for ignoring her warning about the architect’s philandering.

“Christie and I have talked recently and I have privately apologized to her, but, given the public nature of their divorce and custody battle, I feel a public apology is also appropriate and deserved,” Suzanne Shaw wrote in a letter obtained by The Post Thursday.

Shaw said she was sorry for bad-mouthing the model by saying in 2012 that “it was the black cloud of Christie Brinkley’s hate” that had tainted Shaw’s marriage to Cook — when he had actually been continuing his skirt-chasing ways.

“Christie was wrongly vilified as being an embittered ex-wife,” Shaw wrote. “I now believe she had every right to do what she did by taking a public stand; she was only trying to protect her children and have the truth be told. Given the nature of Peter’s behavior, and battles for sole custody of their children, it was necessary for her to confront him publicly.”

Christie’s six-year marriage to Cook imploded in 2007 after she learned of his affair with 18-year-old office clerk Diana Bianchi. Cook rebounded by getting hitched to Shaw, who stood by his side during his ongoing court battles with Brink­­ley. During a 2012 hearing, Brinkley tried to warn Shaw about Cook’s infidelity.
