Things are looking up for "Real Housewives of Beverly Hills" star Kim Richards.

Checking out of an undisclosed rehab facility last week after a successful month-long stint, the Bravo reality star and mom of three children is doing "fabulous," according to her sister Kathy Hilton.

"Kim is on her way. She is having a good time," Hilton told Us Weekly on Sunday's Golden Globes red carpet of Richards, 47, who attended the annual Weinstein post-show party.

Though Hilton insists Richards is "doing well" after being discharged, the reality star's stint in rehab wasn't easy at the time. "She tried to leave and ended up coming back," one insider told Us in December, adding that the former child actress was "very defiant."

"Kim's alcohol addiction along with other substance abuse problems has been obvious for quite some time," a close pal told Us in early December, shortly after the TV star sought treatment. "It's really good that she's finally getting help."
