"It's been harder to not have her on because she was so easy to play off of," Rinna says in a preview clip for Wednesday's Kocktails with Khloé. "She knows that genre. She knows what she needs to do. She plays the game. Whatever it is, it was really easy."
Glanville, 43, exited the show in June after four seasons. Rinna says losing the wine-throwing castmember forced the remaining ladies to adjust to continue to maintain the drama in Glanville's absence.
"We all really liked each other, so it made it much more difficult," says Rinna, 52. "I missed her. And then I didn't."
Following the news of her exit, Glanville spoke to Howard Stern, to counter rumors that she was fired from the show.
"I didn't want to do the show again. I took so much heat. I was doing things to my own detriment that I couldn't explain … like throwing wine in someone's face," she told Stern. "I'm not sure why. And then I slapped Vanderpump, I'm really not sure why. But at the end of the day, I got so much hate on social media."
Kocktails with Khloé, airs Wednesdays (10 p.m. ET) on FYI.
