Kelly, 43, spoke with PEOPLE on Thursday, August 8, about the new RHOC season that premiered two days earlier.
The outspoken TV personality talked about the footage from the premiere where she said that her and Vicki, 57, have nothing in common.
"What I used to have in common with Vicki is that she used to be fun," Kelly said. "We used to get our hair done together, our nails done together, those are kind of things that we had."
"But, you know, she's a grandma. I'm not a grandma, I have a young daughter, her kids are all grown," Kelly continued. "She's more like a senior citizen to me."
Kelly then brought up Real Housewives of New York City star Ramona Singer in reference to the OG cast member. "Even though Ramona is a bit older, she acts like she's my age. I feel like when I look at Ramona, I feel like Ramona is my sister. When I look at Vicki, I look at her as like AARP."
Kelly also claimed that Vicki isn't handing her season 14 demotion so well. She's now in the role as a friend of the 'wives, a first for her since the show premiered in 2006.
The former RHOC besties had a falling out last year when Vicki set up Kelly's ex-husband Michael Dodd with another woman.
Tensions escalated between them when Vicki accused Kelly of doing cocaine during the RHOC season 13 reunion in November 2018.
