Kyle Richards boldly pronounced her former friendship with "Real Housewives of Beverly Hills" cast mate Brandi Glanville null and void.

"We really didn't have a foundation to begin with," Richards recently told Entertainment Tonight of her relationship with Glanville. "It's not like a friend you had a falling out with and you missed them, so there's no love those there."

All Richards' issues with Glanville come just as rumors run rampant that her sister Kim Richards is set to make her return to the show and has already begun filming scenes.

While Kyle Richards readily admitted having to spend all of last season without her troubled sister around was "really weird," that statement should hardly be interpreted as meaning all is well and good between the two siblings.

"We'll probably always be a work in progress," Kyle Richards recently told Bravo network honcho Andy Cohen on his radio show. "We have a very difficult relationship and we will probably always be a work in progress."

Nothing about the last year has been easy for Kim Richards. The 51-year-old reality star has spent much of the year in and out of rehab facilities, and at one point, she was even jailed for public intoxication.

Four months after that meltdown, she was again arrested at a Van Nuys Target store for allegedly trying to steal $600 in merchandise. All Kim Richards' troubles led producers to fire her from the show and strongly hint they never planned to work with her again.

That all changed after she again went to rehab and spent the last several months apparently staying clean and sober.

Bravo recently released a preview trailer of the upcoming sixth season, which suggests that much of the upcoming season will be spent with Kim Richards getting readjusted to the landscape, and butting heads with co-star and longtime nemesis Lisa Rinna.
