Happy Birthday, Pippa Middleton! (PHOTOS)

The world’s favorite royal sister, Pippa Middleton, celebrated her 28th birthday Tuesday afternoon by grabbing a cup of coffee in London, England.

Pippa, who made a name for herself at the royal wedding of her sister, Kate, and Prince William in April, braved the rainy weather in a white lace dress, black blazer, sunglasses and rain boots, and looked down to business as she made her way through the city.

We’re sad that Pippa’s birthday was dampened by showers, but when your sister is the Duchess of Cambridge, we’re guessing today wasn’t all that bad for the 28-year-old beauty.
