Taylor Swift was a bridesmaid at her BFF Abigail Anderson’s wedding this weekend. The two have been friends since they were teens — in fact, Anderson was the inspiration behind one of Swift’s first songs, “Fifteen.” Anderson has accompanied Swift to award shows, she’s been in her music videos, and she has attended every one of her 4th of July parties…but we digress.

Anderson married her love Matt Lucier in Martha’s Vineyard on Saturday, and Swift was one of the bridesmaids.

Swift looked like an Old Hollywood starlet in her burgundy gown, but when people started knocking drinks back and it was time for speeches, Swift got pretty candid.

In a video posted online, we can hear a snippet of Swift telling the story of her bestie having bathroom sex with her now-husband.

Taylor is on the mic and strolling the dance floor, completely at ease, and telling the audience, “She’s running after him, there’s falling, there’s stumbling. They make it to the bathroom and I can hear sounds that I can never unhear. And then there’s silence.”

You can see Anderson’s shocked face in the video.

Clearly, this video was taken by a wedding guest. We’re guessing one of the bridesmaids posted this as an Instagram story and had no idea that the private investigators known as the Swiftiverse would find it.

Fans actually camped out outside the church for a glimpse of Swift at the wedding, but because this wasn’t a concert or a Swift event, we don’t blame Swift for focusing on her best friend’s big day.
