Kim Kardashian recently said she wants her "son to look like" her boyfriend Kris Humphries – but what is it about the NBA athlete that makes her mouth water?

"The sexiest thing about Kris is – gosh, there are so many things," the reality starlet, 30, told PEOPLE on Monday at her sister Khloé and brother-in-law Lamar Odom's Unbreakable fragrance launch party in Hollywood. "It's so hard to think of one."

But after analyzing her beau for a few more seconds, Kardashian came to her senses.

"Probably the sexiest thing about him is his personality," she said. "And also, his deep voice."

Humphries, whom Kardashian has praised in the past, was regrettably unable to attend the fragrance launch, which brought out his girlfriend's entire family.
