Kim KardashianSeems Kourtney Kardashian's pregnancy is making someone broody.

Her younger sister Kim Kardhashian has now announced she wants a sproglet.

In an statement sure to have men running for the hills, Kim said on her website yesterday: "I want a baby."

She added: "OK, so maybe not right now, but I can't wait to be an aunt."

It seems Kourt's baby bump is making Kim a tad jealous after they went shopping together in Miami last week.

But the expectant aunt's a little frustrated that her sis doesn't want to know the sex of the unborn baby.

But Kim's not quite so patient.

Kim wrote: "It's really fun, but we have to stay neutral when you're shopping for a baby and you don't know what the sex of the baby is.

"I found that really hard... I just wanted to to shop for pink or blue, haha. I want Kourt and Scott to find out already."

Can't Kim just do a Paris and get a chihuahua?
