Happy Friday the 13th!
Or is it? Is the number 13 lucky or unlucky? Taylor Swift is a big fan of it—in fact, it's been her lucky number from birth.
"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," she told MTV in 2009. "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."
For years, Swift has written the number on her hand before performances.
"Basically whenever a 13 comes up in my life, it's a good thing," she told MTV.

The actress said on Conan in 2009 that she deals with her fear of flying by listening to Britney Spears music, saying, "I know for a fact it's not in my destiny to die listening to a Britney Spears album, so I always put that on in my [headphones] when I'm flying because I know it won't crash if I've got Britney on."

"I'm a very spiritual person. I travel with my crystals. I've got all different colors. It's just something that I'm into," the fashion designer and Spice Girls singer told Us Weekly in 2011. "I am quite a superstitious person. I don't walk under a ladder. If I see a magpie, I salute."

The tennis star brings shower sandals to the court, ties her shoelaces a specific way, wears the same pair of socks during a tournament run and bounces the ball exactly five times before her first serve and twice before her second, according to Men's Fitness.
"I have this weird thing that if I sleep with someone they're going to take my creativity from me through my vagina," Lady Gaga told Vanity Fair in 2010.
"I have a few kind of lucky mascots," Game of Thrones' Jon Snow told Condé Nast Traveler in 2012. "I've got a lucky pen—it's one I've had since I was a kid, and I carry it everywhere. And I haven't lost it yet, I've lost everything else. I'm kind of OCD, actually. Every time I get on a plane I have to touch the outside of the plane three times before I get in."
"If I walk on to an airplane, I always have to go on with my right foot first and tap the outside of the plane," she once told The Insider. "I have always done it for luck."

"For me, there are about 18 things I have to do before I can go out to perform—most of them are too ridiculous to repeat! One is I have to brush my teeth before I go on stage, otherwise I just don't feel smart," the Coldplay frontman reportedly told the Melbourne Herald Sun.
"I knock on wood all day long...constantly," she told Cosmopolitan in 2000. "But I've also flown on Friday the 13th in a storm with a black cat on my lap, so I'm not that superstitious."
"Don't walk under ladders. My mom just walked under one yesterday and I was like, 'Oh my God, I can't believe you just did that!' I've never walked under a ladder, ever," InStyle quoted the actress as saying.
