The 'Shake It Off' hitmaker can’t seem to shake off her obsession with the number 13. Taylor - who was born on the 13th day - credits the number to some of her musical achievements as well, such as her first number-one song having a 13-second introduction. While many view the number 13 as an unlucky one, it seems to be working pretty well for Taylor. Speaking about her obsession with the digits, she told MTV back in 2009: "I was born on the 13th. I turned 13 on Friday the 13th. My first album went gold in 13 weeks. My first No. 1 song had a 13-second intro. Every time I've won an award I've been seated in either the 13th seat, the 13th row, the 13th section or row M, which is the 13th letter."

It was a gift from his father, Eamon Farrell, and it meant so much to the actor that he was apparently offering a $20,000 reward to anyone who found it. A source told The Sun: “Colin has had this lucky leather belt for so long he just can’t bear to get rid of it. The thing is literally coming apart at the seams. The belt has undergone numerous alterations, like having extra holes punched in it and extra leather added since he has gone through so many weight changes.”

Before Heidi Klum was a supermodel, she was just another kid with baby teeth. But unlike every other kid, she couldn’t bear to part with her baby teeth and has been carrying them around in a little bag as a “good luck charm.” In a 1998 interview, the model said: “I carry around a little bag of my teeth. We don't have a tooth fairy (in Germany), so I put them in a little bag. Little ones, big ones. Those were like, wisdom ones. I don't know if it's good luck, it's just a crazy thing that I do."
