But as tight as Taylor is with her celebrity besties, it was a civilian named Abigail Anderson that first had Swifty trading secrets and telling fortunes with those little folded-up paper thingies.
Taylor and Abigail met when they were both 15 and they've been joined at the hip ever since. So when Abigail turned 25 over the weekend, Taylor surprised her with a surprise performance from her favorite singer/songwriter/emo heartthrob:
That's Chris Carrabba from the band Dashboard Confessional, and if you're a girl of a certain age who's into sensitive guys, you probably spent a good chunk of your high school days trying to decide if you were gonna marry him or the dude from Bright Eyes.

This girl makes dreams come true. She's like the Make-A-Wish Foundation for people who are only dying because of the totes cray gossip that she just told them.
