Real Housewives Meltdown! Brandi Glanville & Lisa Vanderpump Confront Kyle Richards Over Allegations Husband Is Cheating

The only thing the producers of The Real Housewives of Beverly Hills need to do is let the cameras keep rolling because the drama is at an all-time high with a shocking confrontation leading one of the cast members to the verge of quitting.

During filming for season four of The Real Housewives of Beverly Hills last week, Lisa Vanderpump and Brandi Glanville confronted Kyle Richards about allegations that Mauricio Umansky has been cheating on her, RadarOnline.com has learned exclusively.

The situation became so heated and intense that Kyle wanted to quit the show!

Although hunky Mauricio has previously denied womanizing, Lisa and Brandi decided "to confront Kyle about it on camera," a source told RadarOnline.com.

"They absolutely blindsided her, and were relentless.

"Brandi maintained she had solid information to prove that Mauricio has been cheating on Kyle. Kyle became extremely upset, and refused to listen to the girls. She felt especially betrayed by Lisa because they had once been so close."

The interaction was brutal and when it was over the hit show almost lost Kyle.

Kyle was "so upset and disgusted after the confrontation, that she called producers of the show, and told them she wanted out," the source said. "

Producers were able to talk her out of it, but Kyle is extremely unhappy with how season four is unfolding."

As RadarOnline.com previously reported Kyle, who has four children, told us she is ready to have another baby!

“Yes, I want more babies,” the Real Housewives of Beverly Hills star said. “I wish I’d done it right after Portia.”

Kyle, 44, said that she sees other women older than 40 having children, and she wants to do it again too.

“Halle Berry is older than me,” she said about the Oscar winner who announced that she is expecting her second child at 46.

That desire for more children is a stark contrast to the confrontation she faced about her husband.
