Fans of Food Network guru Bobby Flay were shocked when news broke that the married TV
chef reportedly had been involved in a three-year affair with his assistant, Elyse Tirrell.

And though an eyewitness at Flywheel Sports in NYC tells 'Closer,' “I’ve met [Elyse] many times,” and describes the 28-year-old as “very sweet” with “an innocent demeanor,” the allegations from Bobby’s wife of 10 years, 'Law & Order' star Stephanie March, 40, of a not-that-innocent affair between Elyse and her 50-year-old boss is the reason Stephanie kicked him out of their home.

After Stephanie confronted Bobby with her suspicions, they entered couples therapy together, but she questioned his commitment when he began canceling appointments.
