Tensions ran high on Monday's edition of The Real Housewives of Beverly Hills Monday, as Yolanda Foster confronted Taylor Armstrong about the whispers she'd been hearing that Taylor had been "talking about her behind her back."

The stunning former model invited her castmates to ex-husband Muhammad Hadid’s opulent mansion, as she finished redecorating the palatial digs.

Yolanda said she decided to confront Taylor after hearing the chatter from castmates Brandi Glanville, Lisa Vanderpump and Kyle Richards.

At one point, the Holland-born beauty pulled Taylor aside and said, "You know, I wanted to ask you ... I hear from all the girls in the group that you have an issue with me -- do you know anything about it?"

Taylor, not breaking stride, smiled as she said, "No … what issue would I have with you?"

"I heard it like three times," Yolanda said, "so I figured tonight I have to bring it up."

Taylor, in an off-camera interview, said she didn't get into detail with Yolanda because the get together didn't "feel like the right time" for a pow-wow. She admitted the tension with Yolanda isn't so much about Yolanda, but that Yolanda's husband David Foster was once married to her good friend, Linda.

Kyle told Yolanda about the connection at the party, though she already knew, as Yolanda told Kyle that Taylor's friend told her husband David "that she still loves him, and wishes they were still together."

Not missing a beat, Yolanda said, "Obviously Taylor is lying about the tension, so I plan to just wait for Taylor to gather the courage to come to me and say what she thinks."

On her Bravo blog Monday, Yolanda said she'd hoped she could smooth issues over with Taylor because "trash talk is poisonous and a bad habit.
