Real Housewives of Beverly Hills reality star Kyle Richards recently spoke out about the season three reunion, and admitted that she felt "attacked" by co-star Lisa Vanderpump.

The 44-year-old reality star was accused of not being a true friend to Vanderpump, who is now her former best friend. Richards revealed that the way Vanderpump treated her, hurt her feelings.

"I was very hurt at the reunion. I felt attacked by her," Richards told RadarOnline.com about Vanderpump.

The co-stars built a strong friendship during season one, but things changed when season two came around. The former friends have not been able to mend their friendship and Richards said she isn't it let the drama get the best of her/

"Life's too short. I choose to get over things and get on," she said. "I'm a happy person and I can't hold onto things like that."

Sources said that Richards and Vanderpump's relationship is much more than television.

"Kyle and Lisa's relationship will never be repaired and it's more than just the stuff you see on the show," a source said.

"Kyle and her husband (Mauricio Umansky) shot a pilot of sorts for a spinoff show based around his real estate business at the same time Lisa was shooting Vanderpump Rules. They were in competition, from what I understand, because the network wanted to to add a spin off from the Beverly Hills franchise and decided to put Lisa and Kyle to the test," the source revealed.

Sources said that Richards is jealous of Vanderpump's show Vanderpump Rules which first first began airing on the Bravo TV network in January. So far the show has been a success, which sources indicated that Richards is jealous because her pilot was never picked up.

"I think that hurt Kyle's feelings a bit, because she wanted that for herself and for her husband," the source added.
