The new royal baby is here! Kate Middleton and Prince William just left The Chapel Royal at St. James’ Palace with the newly christened Prince Louis. Louis' siblings Princess Charlotte and Prince George were in attendance as well, along with his aunts Pippa Middleton and Meghan Markle, uncles, Prince Harry and James Middleton, and both sets of grandparents. But seeing as this is only the third public appearance little Louis' ever made (the first being when he left the hospital the day he was born), the newest prince was the real star of the show today. Here, all the adorable photos of the youngest Cambridge.
