On Thursday, hours after Richards was arrested at the Beverly Hills Hotel, the Real Housewives of Beverly Hills star took to her blog, where she expressed her love for Richards, and told her she'd "always be here" for her.

"Kim, love having you as a BFF. I’m always here for you, and I hope you are always here for me," she wrote. "You are a strong chica, and I know your family is better for it. You are hilarious, and I love our funny talks and text-offs. Laughter is the best medicine. I heart you."

Although Glanville and Richards initially had words with one another when Glanville joined the show during season 2, they eventually put their differences aside, and by season 5 they were close friends -- at least on-screen.

While Richards told Glanville she was her best friend, as Glanville revealed during season 5, the two haven't seen one another since the Real Housewives of Beverly Hills season 5 reunion was filmed several weeks ago.

At the end of last month, during an episode of her podcast, Glanville confirmed she and Richards hadn't seen one another, but said she had texted her fellow Bravo star after the series wrapped.
