Bobby Flay's estranged wife Stephanie March claimed that she had nothing to do with "cheater" airplane banner during the celebrity chef's Walk of Fame ceremony on Tuesday, June 2. The "Law & Order: Special Victims Unit" star denied she's involved in the incident through her lawyer Deborah Lans, who said, "Stephanie is absolutely not behind [this]."

On Tuesday afternoon, Bobby was honored with a star on Walk of Fame for his work both on TV and in the cooking world. When he delivered a speech, audience were astonished by sudden appearance of a green prop plane flying overhead and carrying a banner that read "cheater."

According to an eyewitness, the plane emerged nearly at the same time Bobby jumped onstage and it continued circling the area until the Food Network star finished speaking.

Many people have since speculated that Stephanie was behind the stunt. The allegation seemingly stemmed from reports that Stephanie accused Bobby, who filed for divorce from her in April after 10 years of marriage, of having love affair. She claimed that Bobby cheated on her with his assistant Elyse Tirrell for almost three years.

However, a rep for Bobby strongly denied the cheating rumors in April, saying, "We will continue to refrain from responding to the continued efforts by certain parties to spread rumors and innuendo. This specific allegation was in a letter sent from one attorney in this case to the other."

"It was written and then leaked specifically to try to insert this story into the press, and that's unfortunate," the rep added. "Even more unfortunate is that all of this is being done in order to renegotiate a prenuptial agreement that was agreed to over a decade ago and never amended during the marriage."
