The Duchess of Cambridge. Kate and her Husband Prince William gave birth to a royal baby boy at 4:24p.m. today. Palace officials said the infant weighed 8 pounds, 6 ounces. I say it’s time for a cupcake celebration. Luckily Magnolia Bakery will be celebrating the royal baby boy announcement with two special cupcakes! Readily available at their NYC, Chicago, and Los Angeles locations! Don’t fret if you don’t live in one of these cities, Magnolia Bakery now ships nationwide as well. Congrats to the royal couple and their new bundle of joy!
