"Tristan and I definitely talk about starting a family. He wants to have five or six kids with me and that's lovely. We could start at one and we could grow from there," she added in a confessional shot.
"It's scary. It's a really big step."
People reported later in the month that Kardashian and Thompson, a power forward for the Cleveland Cavaliers, have discussed "both a wedding and a baby."
"She really wants a baby," a source said of Kardashian, who is aunt to six nieces and nephews, including Saint West and Dream Kardashian. "She hopes it will happen soon."
"[She] is very happy and positive about her future with [Tristan]," the insider added. "She is absolutely hoping for an engagement."
Kardashian finalized her divorce from Lamar Odom in December after initially splitting from the former NBA player in 2013.
Odom confessed he was a "scumbag" to the reality star while discussing his drug use in a recent essay for The Player's Tribune.
