London is buzzing with rumors that Kate Middleton has another royal bun in the oven.

A close friend of the Duchess says that she and Prince William are set to give their firstborn, Prince George, a little sibling. Jessica Hay, who spilled the beans about Kate's first pregnancy, tells Australia's New Day magazine that she's pregnant.

Jessica says, "I’ve heard it from several different friends of theirs now and they’re saying that they think there’s going to be an official announcement in weeks. Kate’s face is fuller like it was when she was first expecting George and she’s been changing her hair, which could be to disguise the fullness. She has rosy cheeks, she’s letting her greys show again, and whenever she’s out in public, she goes to great lengths to hold something over her tummy."

Prince George, by the way, celebrates his first birthday on July 22nd.
