Kylie, Kendall Jenner Talk Kim Kardashian's Pregnancy and Their Ideal Guys

Sisters talk with Ryan Seacrest about becoming aunts again and older siblings' generosity

Kylie and Kendall Jenner are going to be aunts (again!), but the reality of baby Kimye joining the family hasn't really sunk in.

"It hasn't even hit us yet that [Kim Kardashian] is gonna have a kid!," Kendall told Ryan Seacrest on his KIIS FM radio show Tuesday. "It didn't hit [us] with Kourtney [either] until she was literally in labor."

Kylie, 15, and Kendall, 17, said Kim, Kourt and Khloé are all "so generous!"

Meaning? "They let us borrow pretty much anything," Kylie said.

And having three awesome big sisters will certainly come in handy when Kendall and Kylie, who just launched their own collection with PacSun, need relationship advice.

When asked what qualities their ideal guy would possess, Kylie said "funny."

Also important? "Someone I can be myself around," she said.

Kendall agreed with her little sis, adding on, "I like tall, 'cause I'm tall."

Tall, funny, (and we're guessing) family-oriented guys? Yep, we'll take one of those, too.
