Supermodel Christie Brinkley's cheating hubby, Peter Cook, paid $300,000 to his former teenage lover to keep her from singing about their torrid affair, The Post has learned.
Cook's payment to then-20-year-old Diana Bianchi last March came in exchange for a promise not to sue him for sexual harassment.
The Post first reported last year that a deal had been made - but terms of the confidential settlement had been kept secret until yesterday.
Two sources familiar with the deal said Cook, 49, paid Bianchi $300,000, and in return she agreed to never talk about their relationship, which began when she was just 18 years old and working in his Hamptons architectural firm.
