Celebuzz lists nine other celebrity phobias, from the everyday to the downright bizarre: Kristen Stewart: She's been scared of horses since breaking an elbow as a child, but managed to ride in Snow White and the Huntsman. "I just had to not think about it," she says. Johnny Depp: The actor has a weird tactic for dealing with his fear of clowns: He surrounds himself with "clown posters, clown paintings," he says, in the hope that they "will ward off all evil." Matthew McConaughey: He's scared of shirts. No, just kidding: It's revolving doors that terrify him. Tyra Banks: Everyone loves dolphins, right? Not Tyra. She once said she feels "anxiety and panic" whenever she even thinks about them, noting, "It's happening right now." Click for the complete list, which includes a celebrity who's afraid of … plants?! Plus one who hates butterflies.
