Kyle Richards began filming the sixth sesson of The Real Housewives of Beverly Hills over the summer without her sister, Kim. However, months later, Kim rejoined the show, and Kyle couldn't be happier.

Kyle Richards Just Silenced A Major 'RHOBH' Rumor

Although Kim went through hard times throughout this year, she is now on a better path, and her younger sister is happy to have her back on the reality series.

"It feels good to me because it felt weird starting without her anyway," Kyle told PEOPLE Magazine at The Real Housewives of Beverly Hills 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 continued. "We were the first ones on the show, so it felt very strange."

During the fifth season of the show, Kyle and Kim had a major falling out. First, during an episode of the series, the two women were seen at odds over the former home of their late mother, which Kim alleged Kyle stole from her (Kyle claims she and husband Mauricio Umansky bought her out). Then, during the reunion, Kyle revealed her daughter had been bitten by Kim's dog and nearly lost her hand, but Kim claimed it was nothing more than a little nip.
