U.S. TV chef Bobby Flay, who is currently going through an acrimonious divorce from March, was honoured with a plaque on the famous Los Angeles sidewalk on Tuesday (02Jun15).

However, the glitzy event turned sour as a plane flew overhead trailing a banner emblazoned with the word 'cheater'. Many fans speculated the stunt was linked to March, amid allegations the former couple's marriage broke down due to infidelity, but the actress' attorney has now spoken out to silence the rumours.

Lawyer Deborah Lans tells E! News, "Stephanie is absolutely not behind (this)."

The former couple separated in March (15) after 10 years of marriage.
