Lisa Vanderpump Breaks Down During Tearful Vegas Showdown With Kyle Richards

By Debbie Emery - RadarOnline.com Reporter

What happens in Vegas doesn't always stay in Vegas, especially when The Real Housewives of Beverly Hills hit Sin City!

The cast was there last weekend to shoot a special episode of the show, and RadarOnline.com has exclusive behind-the-scenes details on the drama that went down.

"Lisa Vanderpump had a huge break down on the plane ride home," an insider exclusively revealed. "She and Kyle Richards have been working hard to repair their relationship after last season and things came to a head."

As RadarOnline.com previously reported, the British reality matriarch recently told Richards that she had better get in line, and either be with her or against her.

After playing hardball just a few months ago, Vanderpump showed her sensitive side coming home from the Vegas trip, much to the surprise of all her costars.

"Lisa was talking about how hurt she had been by Kyle turning on her at the end of the season and she burst into tears," the show source told RadarOnline.com.

"None of the women had ever seen Lisa cry like that and they were completely in shock.  Kyle felt awful and was doing everything she could to comfort her."

Luckily, the midair meltdown had a positive side affect by reuniting the old allies. "Their friendship is in a much better place but it hasn't totally healed yet," said their pal.

Meanwhile, newcomer Yolanda Hadid, the wife of music mogul David Foster, watched in amazement at the craziness unfolding before her, and may already be having regrets about signing on for life in front of the cameras.

"It seems like Yolanda was unprepared for the level of drama that comes with filming this show. She's kind of out of her element. Every time there was a fight or a breakdown, she was in disbelief. After the trip was over, she told friends she can't believe that grown women act this way," said the insider.

Another source earlier revealed to RadarOnline.com that Hadid's mellow nature is far from captivating TV. "The other ladies are clashing with each other all the time, there are a lot of crazy emotions involved, but Yolanda isn’t causing any drama or adding any drama  - she is a bore!"
