(Cover) - EN Showbiz - Kim Kardashian has "reserved" baby names beginning with the letter K.'

The newly-engaged reality star, 32, plans to marry professional basketball player Kris Humphries, 26, this summer after he proposed with a 20.5 carat custom-designed ring last month.

Kim, who has been dating the sports star for six months, is already considering names for her children, according to younger sister Khlo. The star has recalled the moment that Kim informed her family of her relationship with Kris during a casual conversation about baby names.

"When Kim was in New York, she was trying to be single and hang out and she kept Kris very secretive," she explained to E! Online. "When she was like. 'Oh, what K name should Kris and I have?' And I was like, 'Um, what? What are you talking about? Like, we didn't even know you had a boyfriend.'"

Khlo, who is married to Lamar Odom, says Kim has already earmarked possible names for her future children with her beau. The raven-haired beauty is apparently "reserving" names beginning with the letter K' in keeping with the Kardashian family tradition.

"Kim is the only crazy person that would actually like, reserve," she laughed. "Lamar and I like baby names, but I'm not going to say, 'No one else can have this name!' "

Meanwhile Kourtney, 32, says Kim is welcome to her desired names, as she isn't keen on the idea of naming her children with the K' tradition in mind. The stunning star has son Mason with her partner Scott Disick .

"I clearly haven't stuck with the 'K' name thing going on, hence Mason. So everyone else can have the 'K' names. That's fine with me," she said. (C) Cover Media
