Taylor Swift [1] played a big part in the nuptials of her childhood BFF, Britany Maack, to Benjamin LaManna on Saturday: she was the maid of honor. The singer, who was on hand to support her friend in Pennsylvania, looked gorgeous in a Reem Acra blush gown [2] and was all smiles while posing for photos. Naturally, Taylor took to Instagram [3] and shared a group shot from the event, writing, "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!"

Back in May, Taylor shared her excitement over being part of the wedding party, gushing to People [4], "I've never been a maid of honor before. This is my first time, and it's really, really important to me because this is my best friend, who I've known since I was born. And she's marrying someone I've known since I was 4."

Although Taylor attended the event solo, she recently reunited with boyfriend Calvin Harris [5] after her triumphant return to the Grammys [6] on Monday, adding to their many sweet moments together [7].
