After four unsuccessful attempts at wedded bliss, Christie Brinkley has no plans to walk down the aisle again.

“I would never get married again,” the iconic former supermodel says in Ladies Home Journal’s July 2009 issue. “With what I know I don’t see why anyone would get married.”

We can’t say we blame her. Just last summer, Christie went through a very public, very nasty divorce battle with architect Peter Cook, who admitted to having an affair with 18-year-old assistant Diana Bianchi during their marriage. Peter also copped to spending thousands of dollars on Internet porn.

“I feel like I should apologize to everybody for them having to read all of that tawdry stuff, and having it delivered to their kitchen tables when their kids are around, you know?” Christie says.

The spat ended with a $2.1 million settlement for Peter and custody of the couple’s two children – Jack and Sailor – for Christie. In the new interview, Christie revealed that it was singing former flame Billy Joel who helped her through that difficult time.

“Billy’s great. He’s godfather to Jack and Sailor, and you know there have been times when I have had to spend time with lawyers or whatever and he’s babysat,” she said. “He lives nearby, so he’s like, ‘Send ‘em over here!’”
