Reality star Kim Richards seems to be getting her life back together after a series of stints in rehab over the last year.

A source tells ET that the former "Real Housewives of Beverly Hills" star has moved into a cozy apartment in Westwood, California, and that the 51-year-old Richards is doing great in the new condo.

"Kim is doing really well," ET's source shared. "She’s focused, she’s sober, she’s happy. The place is so great!"

The apartment is reportedly a one-bed, one-bath space in a complex with full amenities and a gym. While the place is somewhat small, the neighborhood is upscale, and while it's unknown how much Richards is paying in rent, spaces in the complex can go from $3,000 to $5,000 a month.

Richards, who recently appeared in "Sharknado 3," is no longer a member of the "RHOBH" cast. She exited the show following a series of legal run-ins, including an arrest for shoplifting.
