Taylor Swift , whose list of best friends seems almost as long as the list of artists who should have won the Grammy for Album of the Year , celebrated her childhood friend's wedding on Saturday. We're assuming the happy couple didn't choose "Famous " as their first dance song.

Swift served as maid of honor to Britany Maack, who she grew up with in Pennsylvania before going on to conquer Nashville.

"I met her when I was 10 days old, and him in kindergarten. Now they're married and I'm the happiest maid of honor ever. Congratulations @britmaack and Ben!" she captioned a sun-kissed photo of the wedding party on Instagram.
