Whether Kim Kardashian is having a boy or a girl is possibly one of Hollywood’s worst-kept secrets. The fashionista and her just-as-famous sisters refuse to reveal the gender of kid Kardashian, teasing viewers to watch the premiere of “Keeping Up With The Kardashians” to find out.

When the 32-year-old reality-television star was just a few months’ pregnant, rumors began to circulate that the presumed father of her child, rapper Kanye West, wanted to name the baby, who was thought to be a girl at the time, North.

Although Kardashian disregarded the gossip about the child’s name and sex, she said the name North would be a cute idea. Most recently, baby-shower invitations for the Kardashian-West child leaked online. The Daily Mail posted photographs of little music boxes, each with a ballerina, that were sent to every guest invited to the shower, furthering the belief that the child inside the reality-TV star’s womb is a girl. If it turns out that she’s actually having a boy, she might have just pulled off one of the best celebrity surprises to date.

The expectant starlet was scheduled to have her baby shower this weekend, and, according to her sister Khloe Kardashian-Odom, West felt “weird” about being at the shower. “I think Scott [Disick] and Lamar [Odom] might bring Kanye,” she told Ryan Seacrest Friday on his KIIS-FM morning radio show. “That might happen at the end. That's what we were all deciding. Kanye said he feels like it's weird for him to be the only guy. I'm like, it happens to all girls, so if all the guys come at the end, it's good.”

Someone the famous sisters definitely wanted to be there is their younger brother Rob Kardashian. “I want Rob to be there the whole time because I feel bad,” Khloe Kardashian-Odom explained. “He’s, like, left out of all this stuff, so I said come the whole time. I don’t know if he is.”
