In honor of Friday the 13th, find out which of your favorite celebrities are superstitious.Cameron Diaz has a necklace given to her by a friend that’s supposed to ward off the effects of aging. Cate Blanchette reportedly keeps her “Lord of the Rings” elf ears on her mantel for luck. It is said that Meat Loaf has two stuffed teddy bears that he keeps as good luck. Cuba Gooding Jr. won’t tell what his good luck charms are, for fear they won’t work if he does, but he does admit to having them. Other superstitious stars are reported as Richard Gere, Sharon Stone, and Cybill Shepherd who are said to believe in the powers of crystals. The term “Break a leg” is a superstition used in the acting profession, so maybe superstitions are more prevalent in the celebrity community. Either way, watch out for the black cats today!
