Diana Bianchi Picture

Diana Bianchi is the home-wrecking teen that broke up Christie Brinkley's marriage to Peter Cook. At only 18, Diana Bianchi was the Long Island architect's assistant before she let him tap that. Silly.

The aspiring singer is back in the news now because she will be testifying at the public divorce proceedings of Brinkley and Peter Cook. That should be terrible for all involved ... entertaining, though.

Diana Bianchi, we look forward to hearing from you some more
. Just don't sing, k?
