may not be ready to have kids just yet, but the reality star says that motherhood is in her future one way or another.
"I think it is such a very unselfish and amazing thing to do," she told PEOPLE at a question and answer session – "The Kardashians: Up Close and Personal" – at the Hilton hotel in Atlantic City Saturday night. "If I couldn't have kids, I probably would adopt. If I could have my own, I would have my own."
In the meantime, Kardashian says she's looking for new home, but does not plan to move in with her boyfriend, NFL star Reggie Bush, any time soon.
"I have done this before so I know by trial and error. I don't think I would ever live with someone unless I'm engaged," Kardashian said. "I'm really firm on that. I have done it before."
Instead, Kardashian says she's looking for a place to call her own. "It feels really good to be able to buy a place by myself," she said. "It is time for me to move. I have lived in a condo and it's just time. I've always wanted to buy a big house myself and it is so gratifying to be able to."
But her boyfriend will have an open invitation to her new place when she finds it. "Obviously when you're home you're at each other's house every night," she said. "I just think it is so important for a women to keep her independence."
