Taylor Swift may be everyone's favorite dancing queen at awards shows, but apparently, she pulls out those moves at weddings, too!

The 26-year-old pop star was a lovely maid of honor to her childhood best friend, Britany Maack, who said "I do" to another one of Swift's pals, Benjamin LaManna, earlier this month at Sacred Heart Chapel in Reading, Pennsylvania.

On Saturday, the blushing bride shared a video -- which features beautiful tracks by Christina Perri, Bright Eyes and Walk the Moon in the background -- showcasing highlights (and Swift's signature dance moves!) from the special day to Vimeo.

In the footage, Swift can be seen sitting next to Maack at the dimly-lit rehearsal dinner as the two look back at memories of the couple on the monitor. The video then cuts to the wedding day, where Swift helps Maack get primped just moments before walking down the aisle.

Dressed in an off-the-shoulder Reem Acra gown featuring silver embellishments, the "Out of the Woods" singer looked as elegant as ever while gracefully making her way to the altar to line up with the rest of the bridesmaids.

After LaManna and Maack sealed the deal with a kiss, the bridal party and guests made their way to the reception, where a spirited Swift took her place at the center of the dance floor. But not before giving a fairy tale-esque maid of honor speech first!

"He would chase her and pursue her through middle school and junior high and high school, and their paths would diverge, and then come back together," Swift recalled. "It would be so magically unpredictable, but at the same time, so incredibly faded just like the best love stories are."

"My favorite accomplishment of my entire life is that everything in my life has changed except for me and Britany," she continued. "She was my partner in crime at Brownie's sleepaway camp and she was my date to the GRAMMYs. And little did either of us know that prince charming for Britany would be the kid that sat next to me in class with a bowl cut and a LEGO lunchbox."

As ET previously reported, Swift has known Maack since she was just 10 days old.

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