Things got ugly for Anna Kournikova at an afterparty in Vegas on Saturday night.
The former tennis champ attended the HardBat Classic Ping-Pong tournament earlier, where she refused to play.
"She wouldn't play Ping-Pong because she was really scared that she was going to be bad," a source tells E! News.
Later on, around 2:30 a.m. at Lavo, a guest spilled a drink on Anna's assistant, leading to a shoving and screaming match between her and Anna.
Anna didn't come away unscathed...
"She had some scratches, but I think she was just more embarrassed," a source says of the scuffle, adding that paramedics weren't called. "They were both drunk."
Despite the incident, a source says Anna was never asked to leave the club.
