Singer Taylor Swift has a strong belief in the power of 13. She paints it on her hand before every show because, "13 is my lucky number; for a lot of reasons," she explained in an article to MTV in May 2009.

"It's really weird … I was born on the 13th," she continued. "I turned 13 on Friday the 13th. My first album went gold in 13 weeks. My first #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 … Basically, whenever a 13 comes up in my life, it's a good thing."
