Spending the weekend in Sin City, Anna Kournikova took part in the HardBat Classic Table Tennis Tournament at The Palazzo Resort in Las Vegas on Saturday (June 30).

Also attending an afterparty, the former tennis pro ended up having quite the unfortunate experience, as she got into it with another female partygoer at Lavo nightclub.

After a minor run-in, as insider tells People magazine: "The woman came back over and threw a drink on Anna and her assistant. The woman was definitely drunk."

"Anna said she wanted the woman kicked out, but then everything started to escalate and she and the woman started shoving and pushing each other," the source tells, adding, "Anna looked really shaken up."
