Kim Richards

Real Housewives of Beverly Hills star Kim Richards will sit down with Bravo's Andy Cohen for her first in-depth interview since leaving rehab, On Air with Ryan Seacrest reports.

Although two parts of the Real Housewives reunion had been previously announced, a special third part of the upcoming special, in which Richards' interview will be featured, has apparently been added.

Real Housewives' Kim Richards leaves rehab

Richards, 47, completed her treatment in early January. She exhibited questionable behavior during the show's second season — most recently locking herself in a bathroom at a restaurant opening. During an early Season 2 episode, Richards attributed some of this behavior to her regimen of prescription medication, which she said included anti-anxiety medication Lexapro, the antidepressant Trazadone, and Topamax, an anti-seizure medication.

Kim "is in a much better place now," her sister and co-star, Kyle Richards, told Seacrest earlier this month on his radio show.

Part 1 of the Real Housewives of Beverly Hills reunion airs on Monday at 9/8c on Bravo.
