The Real Sisters of Beverly Hills are back!

After a rough year, Kim Richards will appear on Real Housewives of Beverly Hills again, and her sister Kyle tells PEOPLE she’s excited to have Kim back on the show.

“It feels good to me because it felt weird starting without her anyway,” Kyle, 46, told PEOPLE at the RHOBH season 6 premiere party at the W Hollywood Hotel on Thursday. “She was taking care of herself, so it made sense, but it just felt weird.”

“We started this together,” she continues. “We were the first ones on the show, so it felt very strange.”

Kyle said Kim, 51, who has struggled with sobriety, is “doing good.”

Kim was arrested in April and charged with trespassing, resisting and officer and battery on a police officer. Shortly after the arrest, she checked herself into rehab. She was also arrested for shoplifting at Target but avoided jail time by taking plea deals in both cases.

The Real Housewives of Beverly Hills airs Tuesday (9 p.m. ET) on Bravo.
