Friday the thirteenth is an unlucky day, but a rabbit’s foot brings good luck. These are some common superstitions. These beliefs are not based on logic or reason, but most of us have our quirky superstitious behaviors and this goes for celebrities too. Check out some of the famous people who believe in superstitions.

Cameron Diaz

 

 

 

 

 

 

The actress believes in lucky charms. According to Elle, she often wears a lucky necklace given to her by a friend in order to ward off aging. Diaz told Cosmopolitan, “I knock on wood all day long…constantly. 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.”

James McAvoy

 

 

 

 

 

 

McAvoy doesn’t mess around when it comes to superstitions, especially those his grandmother believes in. He said, “On the first of every month I have to say ‘White Rabbit’ to the first person I see. My grandmother taught me that, it’s good luck to say it.”

Jennifer Aniston

 

 

 

 

 

 

She has revealed to XFINITY Entertainment that she has a superstitious flying routine, “If I walk onto an airplane, I always have to go on with my right foot first and tap the outside of the plane,” she said. “I have always done it. For luck. Someone told me to do it and I don’t remember when that was. But it’s kind of stuck.”

Paris Hilton

 

 

 

 

 

 

Of her superstitions, Hilton said, “A little bit. Knock on wood if someone says something that I don’t want to happen. Or I always make a wish at 11:11.”

Colin Farrell

 

 

 

 

 

 

Colin Farrell revealed that he always wears the same boxer shorts whenever he starts shooting a new movie. They are “covered with shamrocks, and the waistband says, ‘The luck of the Irish.'”

Kristin Chenoweth

 

 

 

 

 

 

The Broadway blonde who also played a role on Glee, has a fear of walking under ladders and a superstitious pre-show routine. She told Instyle, “I have a fear of walking under ladders. It’s probably because it’d be much easier for me to do so than many people. I also say a prayer right before I got out on stage so that lights never fall on me.”

Emma Roberts

 

 

 

 

 

 

Emma shares Chenoweth’s ladder superstition. “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,” Roberts told Instyle.

David Annable

 

 

 

 

 

 

Brothers & Sisters star David Annable revealed his superstitious nature when it comes to caffeine. “I think I’m superstitious about sort of random things. I think I have a weird OCD thing with coffee. I have to have my two Splendas, but the cap has to be measured with the black line in the cup. It’s really strange, but I do it every morning. It makes me feel better,” he said.

Megan Fox

 

 

 

 

 

 

Megan has Britney Spears as her lucky charm! In an interview with talk show host Conan O’Brien, Fox said that always listens to Britney Spears when she is flying because, “It’s not my destiny to die listening to a Britney Spears album.”

Rainn Wilson

 

 

 

 

 

 

The Office star follows an age-old theater rule. “I come from the theater, and you never say the word Macbeth in the theater. I believe in that because I said it once and a light fell from the ceiling and crushed my foot,” Wilson said.

Jessica Alba

 

 

 

 

 

 

Jessica Alba passed out leather bracelets at her baby shower with a prayer on them and ordered the recipients not to remove them until after the birth of her daughter.

Leighton Meester

 

 

 

 

 

 

Her good luck charm is a pair of Marc Jacobs heels. She believes these shoes landed her the life-changing role of Blair Waldorf. Having bought them at a time when doing so would’ve made her unable to pay rent. Her mother convinced her, “rent could wait.” She took the advice and the rest is history.
