Things got ugly at the wrap party for 'The Real Housewives of Orange County.'

After Tamra Barney threw wine in Jeana Keough's face, the former Playboy Playmate retaliated, Radar Online reports. The fight then escalated into a physical altercation between Barney and Keough.

Before the fight, Tamra attempted to serve Jeana with a cease and desist letter, claiming that interviews Keough gave about Barney and ex-husband Simon were untrue. This enraged Jeana, and an argument began.

According to one witness, "It was crazy. It looked more like an out-of-control bar scene than a party!"
