Pippa Middleton is officially a new auntie! Now that the Duchess of Cambridge Kate Middleton has given birth to her son on July 22, we're sure Pippa is ready to be the fun aunt to the royal baby. With her fashion sense, this is also probably going to be the most stylish nephew ever. The sisters have always had a close bond as seen here at the Wimbledon Lawn Tennis Championship in 2012. We know the royal baby will be just as close to his stylish aunt. Of course, when the royal baby hasn't been spoiled enough by aunt Pippa there is always uncle Harry.
