The former The Hills star became Kris' stepson when she married his father - who is now known as Caitlyn - but he told Sway In The Morning radio show that he just doesn't really talk to Kris.
Brody said: "Honestly we never talk. It's not that we have a bad relationship, and it's not that we have a good relationship. We just don't have a relationship really.
"I will say this, there's just been a lot of family drama that doesn't even involve me. It involves my parents; it involves the divorce way back when, when that happened. There's just a lot of moving parts in our family, and it's a big family, and Kris and I, we just don't talk.
"That's all I'm going to say. Kris is Kris. Brody is Brody. We will keep it at that. I do like her. I think Kris is a very smart woman. I think she's an incredible mother to her children."
Brody's mother is actress Linda Thompson, who is also mum to his brother Brandon.
The boys have four half-siblings and four step-siblings.
They are stepbrother to Kourtney, Kim, Khloe and Rob Kardashian through the Kris Jenner marriage, while Kris and Caitlyn are parents to Kylie and Kendall, their two half sisters.
They also have half-brother Burt and half-sister Cassandra from Caitlyn's first marriage.
