Christie Brinkley caught her husband cheating with his 19-year-old personal assistant!
That's the shocking story behind the supermodel's sudden marriage breakup, uncovered exclusively by The ENQUIRER.
Christie, 52, dumped 47-year-old husband Peter Cook after a dramatic confrontation between Cook and the stepfather of his teenage mistress right in front of Christie, according to sources.
"The girl's stepdad is a local cop in Southampton (N.Y.) and he initially went to Cook and told him to end the romance," a source told The ENQUIRER. "But nothing happened and then the stepfather found out where Christie and Peter were going to be at an event."
"He went to Cook and told him to end the romance," a source told The ENQUIRER. "But nothing happened and then the stepfather found out where Christie and Peter were going to be at an event."
"He went up to both of them and said right in front of Christie, 'Stop dating my daughter.'" The next day, Christie threw Peter out of the house, according to the source.
Cook, an architect, met the young woman at a toy store last year when she was 18 years old, sources say.
The ENQUIRER has identified her as Diana Bianchi. She is now 19 and is attractive with dark hair.
Cook is Brinkley's fourth husband, and the couple has been married nearly 10 years. They have a daughter, Sailor, 8. They are also raising son Jack, 11, from Brinkley's 11-month marriage to real estate developer Richard Taubman.
Brinkley also has a third child — daughter, Alexa, 20, from her 9-year marriage to singer Billy Joel.
According to the sources, after meeting the girl at the toy store, where she worked as a clerk, Cook then hired the girl as his "personal assistant" at his architect firm.
Said a close source: "He wined and dined her. She's an aspiring singer and he helped her make connections in the music business."
Joseph Bianchi, Diana's uncle, told The ENQUIRER: "It's an emotional time for Diana and she's really dealing with a lot right now."
When contacted by The ENQUIRER, Cook did not deny the affair, saying: "I am happy to reply that I love my wife, I love my children, I have never stopped loving and caring for them, and we are still a family."
Brinkley's publicist Elliot Mintz announced the couple's separation on July 11, saying in a statement: "Her immediate concern is for her children."
