guys...can u tell me why taylor swift is always writing 13 in her hands...????

1. Her Birthday
Taylor Swift was born December 13, 1989. Not only that, but her 13th birthday fell on a Friday, making Friday the 13th like a mini-holiday for the young singer.
2. No Fear of Numerology
If you've ever looked at the track listing for Fearless, you've probably noticed that Taylor kept the album right at 13 songs. Fearless? 13? It's almost like she's taunting the "unlucky" number. Further proof that Taylor has mastered the cursed number: 11 of those 13 tracks spent time on the Billboard Hot 100.
3. The Reminder
Just in case Taylor ever forgets her lucky number, she often has a reminder within arm's reach. She's been photographed several times with the number drawn on her hand and has said she usually has it drawn somewhere on her hand during her shows. In the photo below you can see her with ex-boyfriend Taylor Lautner on the set of Valentine's Day. Not only does she have the number written on her hand, but Lautner is wearing her lucky number on the back of his work-out tank.
4. The Tattoo
If Taylor gets her way (and at this point why wouldn't she?) she'll eventually have her lucky number tattooed somewhere on her body. Last February she was reportedly on the verge of getting the ink done when her parents convinced her to hold off. Keep an eye out for the mark in the future in case she decides she wants that tat anyway.
5. Record Breaker
In 2008 Taylor Swift had six songs debut in the top 20 of the Billboard Hot 100 -- the most hits any artist has ever had debut that high in a single year. She set the record with "White Horse," which debuted at 13.
6. The Twitter Connection
Twitter has no qualms about commandeering existing usernames and handing them over to the actual celebrities with those names. When Taylor set up her account she could have just used her name, but she tacked her favorite number on anyway
7. Paying It Forward
Taylor Swift is no stranger to charitable donations, and when she donates, she likes to send a little extra luck to whoever she's helping out. When she performed for the BBC's Children in Need night, she didn't just donate her time. She also handed the organization the US equivalent of $20,600.
8. Lucky 'Teardrops'
When Taylor released "Teardrops on My Guitar" as the second single off her first album in 2007 it peaked at number 33 on the Billboard Hot 100. When she re-released it with a pop remix the universe signaled its approval as the song climbed to the 13th spot on the Hot 100.
9. Casting Call
Taylor knew she'd found the right guy to play the romantic lead in her video for "Mine" when she came across footage of Toby Hemingway in The Covenant. He was wearing a T-shirt with the number 13 and Taylor took it as a sign.
10. Awards Winner
Taylor claims that every time she's ever won a big award she was sitting in "either the 13th seat, the 13th row, the 13th section or row M, which is the 13th letter."

13 is her lucky number, so she writes it on her hand.

her birthday is on 13th dec.
and her lucky num is 13

It's her lucky number, so during shows she likes to have it on her hand :) I can't explain it as well a TVD_rocks did, but it's also her birthday. :) Hope this helps! :) <13

Because when she wass 13 she got her first 'record deal

It's because 13 is her lucky number. This is why....
"The significance of the number 13 on my hand ... I paint this on my hand before every show because 13 is my lucky number — for a lot of reasons," she explained. "It's really weird."


Not only is it the day she was born on in December 1989, but over the years it has become so much more. "I was born on the 13th. I turned 13 on Friday the 13th. My first album went gold in 13 weeks. My first #1 song had a 13-second intro," she said. "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." said taylor swift herself
