On Tuesday, Vanderpump told Hallmark channel's Home and Family that she was actually under contract at Bravo and that for most of the show's seasons she did have a good experience with the show.

"I'd done something like 140 episodes. So for the most part, it's been incredible - it really has," she told the program. "It's given me such an opportunity to talk about the things I'm passionate about... You know, because I'm a huge supporter of the LGBT community, children with alopecia, Keep the Memory Alive, all those things, so that's been really, really helpful, and I've had a lot of fun doing it. I really have. But last season it was hard."

Vanderpump said that there was a lot of "meanness" on Season 4 of Real Housewives. "I did really take the brunt of that, and it was not easy to go through... At times, I did question my sanity for going back this year."

But, it already seems Vanderpump is having a better Season 5. The reality star's friend Lisa Rinna has reportedly joined the cast and Vanderpump has been seen hanging out with Kyle Richards as well while filming the show.
