Phillips, president of the software giant Oracle, was married to his wife, Karen, during Phillips' eight-and-a-half-year extramarital affair with Wilkins.
When Wilkins learned Phillips was reconciling with his wife, she decided to get even, reports the New York Post. Wilkins spent close to $250,000 on the revenge.
She developed a website and put a billboard in New York's Time Square, one in Atlanta, and one in San Francisco, where Oracle is based.
