Kyle Richards Confronts Lisa Vanderpump [VIDEO]

On Monday's episode, the cast members visited Puerto Rico. But, their trip was dampened when Lisa Vanderpump and her husband Ken left the trip without telling anyone. Kyle Richards wanted to have a conversation with them about who brought the tabloid (detailing Mauricio's alleged affair) to Palm Springs, as she felt betrayed by whoever did it.

Brandi Glanville says that she saw Lisa looking through the magazine some time before, and she believes that she packed it in her bag.

Now, with various bonds shaken over the tabloid fiasco, Kyle is uncertain who to trust and the whole group is tense. Also, the whole group seems to be fed up with Vanderpump's involvement in cast drama.

In the next episode of the Bravo hit show, Lisa Vanderpump will be confronted by the girls at a party, but Ken is not too happy about it. Bravo released a clip from the season 4 finale, giving fans a glimpse of how the confrontation will go down.

Brandi accuses Lisa of packing the magazine her luggage, yelling, "We all sat there looking at it and you said, should we bring this?" She continued, "Then I said no, and then its' in my luggage."

Vanderpump, never one to back down from personal attacks, questioned why Brandi had it saying, "Well, then what did you do with it?" She stuck to her story, mentioning, "I don't remember a magazine."
