Bookmakers are taking bets on the name of the royal baby, with Diana among the favorites.
As a member of the "Jersey Shore's" royal court - if not the queen bee - new mom Nicole "Snooki" Polizzi has some words of wisdom to share with the pregnant Duchess of Cambridge, Catherine Middleton.
"It's hard, but don't stress out!" Snooki advised Kate in the New York Daily News. The 25-year-old reality star and her fiancé Jionni LaValle welcomed their first child, son Lorenzo, in August.
"Enjoy your pregnancy and be excited," Snooki continued, congratulating Kate and Prince William on the news of their impending arrival.

The palace confirmed the royal couple are expecting their first child on Monday, after Kate was admitted to a hospital in London with acute morning sickness.
Snooki, who announced that she was pregnant via an Us Weekly magazine cover, also advised Kate on how to deal with the paparazzi. "Enjoy your time at home - or the castle, in her case - with the baby. Especially the first few months."
Of Kate, she added, "I'm sure she will be an amazing mom."
