Bobby Flay gets Walk of Fame star as "cheater" banner flies overhead

They say revenge is a dish best served cold, but it can apparently also be served with the help of a plane.

On Tuesday, Bobby Flay received a star on the Hollywood Walk of Fame -- becoming the first celebrity chef to do so. But while he was giving a speech on the big day, a prop plane was spotted flying overhead carrying a banner that read "Cheater."

According to E! News, an eyewitness said the plane appeared just as Flay took the stage and continued to circle the area until he was finished speaking.

There's no word on who flew the plane, or why, but many are connecting it to Flay's divorce from actress Stephanie March after 10 years of marriage. March has reportedly alleged that he cheated on her, and the two are said to be at odds over their prenuptial agreement.

According to "Entertainment Tonight," neither Flay nor his family drew any attention to the banner during Tuesday's Walk of Fame ceremony.
