The life of a pop star is grueling. Celebs like Demi Lovato, Britney Spears and the boys of One Direction are constantly in the public eye and have a never ending cycle of performances, TV appearances, and interviews. It's no wonder they start to get a little silly and loopy-- they are probably exhausted!

Not to mention, if you have a camera in your face almost every second of the day, wouldn't you be caught experiencing bouts of silliness just like Rihanna, Lady Gaga and Miley Cyrus? That's what we thought.
