Reality Catfight! Lisa Rinna & Dorit Kemsley Come Face to Face In Vegas

The television drought of Berkin bags, private jets and master closet makeovers is over. The Real Housewives of Beverly Hills are back - and based on Monday night's season eight premiere, tension is just as high between Lisa Rinna and Dorit Kemsley as it left off last season.

Rinna and Kemsley came face to face for the first time after last year's explosive drama, when Rinna questioned Kemsley's use of cocaine in a bathroom. Kyle Richards invited the whole cast on a luxurious quick trip to Las Vegas for birthday celebrations, where it all went down.

"Lisa Rinna deliberately came after me and she did it to defame my character and to hurt me," Kemsley said. "I do have unresolved feelings with her."

Veteran cast member Lisa Vanderpump agreed. "I hope Rinna's learned her lesson.You can't just go around slandering someone's reputation."

Rinna and Kemsley came face to face in the ladies' master suite. A high and mighty Rinna walks in wearing short black minidress broadcasting 'hello's across the massive room.

The episode teases the two duking it out on a rooftop terrace.

"Your words are so low that they can really affect people's lives," a heated Kemsley tells Rinna.

"Listen Dorit, I would like you to see me for who I really am," Rinna responded.

Meanwhile, Kemsley and Erika Girardi surprisingly keep their cool in each other's company - at least for now. It's a matter of time before the infamous Pantygate comes back into the conversation. Girardi was caught not wearing underwear last season and Kemsley and her husband, PK wouldn't let the topic go.
