LOS ANGELES: Anna Kournikova was reportedly humiliated on Miami Beach after losing her temper with a dog owner.

The retired tennis beauty snapped at a surfer who had his puppy on the beach, shouting: “That dog should be on a f***ing leash!”

However, the surfer snapped back: “Maybe you should be on a f***ing leash!”

The exchange prompted passers-by to spontaneously applaud the surfer and mockingly bark at Kournikova.

A source said, “She looked embarrassed and walked off around a corner. She reappeared a few minutes later with three girlfriends who just stood there scowling.”

A representative for Kournikova refused to comment on the alleged incident.
