New York, July 1 Tennis ace Anna Kournikova reportedly landed into a cat fight in Las Vegas after an unknown woman threw a drink at her.

The Russian model was apparently partying with friends at Lavo after attending the Hardbat Classic table tennis tournament.

"(A woman at the next table) threw a drink at Anna. She felt Anna was invading her space," the New York Post quoted a source as saying.

The 28-year-old was said to have "sprung into action", and began yelling at the woman, leaving the player with alleged scratch marks on her neck.

"It was a big fight," said the source.

Kournikova's publicist did not return calls. (ANI)
