Royal fans have been wondering for weeks now if there's a bun banking in Kate Middleton's oven, and it looks like they'll finally find out what's really going on. Rumor has it that the Duchess is planning on making a huge announcement this week, prompting speculation that she might indeed be pregnant with her third child.

According to Celebrity Dirty Laundry on Tuesday, sources say that the royal mother-of-two will begin her stint this week as a guest editor for the Huffington Post UK and she'll supposedly use the opportunity as a platform to make her announcement.

The site says, "Royal watchers are wondering whether or not the Duchess of Cambridge will also let the world know a third Royal baby is on the way."

They further speculate, "Will Duchess Kate break with tradition and share the good news during the Huff Post U.K. guest editor gig? Formal pregnancy and birth announcements usually come from Buckingham Palace. But Princess Kate has never been one to follow Royal protocol."

Other insiders say that it's very unlikely that the Duchess would make the announcement via a news site, especially since she's only working as an editor. She and her husband Prince William already have two children, 2-year-old Prince George and Princess Charlotte, who will turn 1 this May.
