All hail the royal dog! The palace just confirmed that the cocker spaniel puppy seen palling around with the Duke and Duchess of Cambridge is indeed their new pet. The royals aren't the only celebs who welcomed a furry new addition to their family this week—Drew Barrymore and her husband-to-be, Will Kopelman, are also the proud parents of a new pooch. Oliver, their rescue puppy, was first fostered by Twilight's Nikki Reed. Only in Hollywood!

See these two critters and more of our favorite celebrity pets in the gallery now.
