She's not kidding -- you've got to see how ecstatic Taylor looks!
Taylor Swift is a maid of honor!
After taking home three GRAMMYs on Monday, including the coveted Album of the Year award, Swift said "I do" to a friend's wedding ceremony. Her best friend, Britany Maack, tied the knot with another one of Swift's longtime friends, Benjamin LaManna, on Saturday evening at Sacred Heart Chapel in Reading, Pennsylvania. Swift has known Maack since she was 10-days-old.

"I met her when I was 10 days old, and him in kindergarten," Swift captioned the pic. "Now they're married and I'm the happiest maid of honor ever. Congratulations @britmaack and Ben!"
The ladies dazzled in dresses designed by celebrity couturier Reem Acra. Maack's
hand-embroidered ball gown with cathedral veil was a stunner, while Swift looked regal in a blush pink chiffon cap gown with a hand-embroidered bodice.
"Reem does the most amazing bridal designs, and Britany and I were looking through Vogue, and she pointed to this one gown, and I was like, 'I wonder if we could go to the showroom," the Grammy winner told the magazine May 2015, adding that their "amazing" visit to Acra's NYC showroom was "the best day ever."
