Pandas. They're just friggin' lovable, okay? This space would normally be reserved for authors to explain why they've decided to make a list about a certain topic, or to describe that topic so it's perfectly clear what's being discussed. But you don't need any of that this time. It's a list of celebrities who have taken photos with pandas.
And they can be any kind of panda bears. Stuffed. Fictional. Authentic actual panda-type animals. Even Photoshopped applies (though I've limited myself to just one example... can you spot it?)
