Hot buzz: Another Kardashian baby's on the way!

Now that Kim and Kanye's wedding is over, what's the next big life event for the Kardashian clan?

A baby!

Us Weekly says Kourtney Kardashian, 35, and her sweetie Scott Disick are expanding the family, citing "multiple sources."

No one in the family has tweeted a peep about it. And Kourt's rep tells us "no comment."

If all goes as Us says, the new lil K - due in December - will join brother, Mason, 4, and sister Penelope, who'll be 2 in July.
