Taylor Swift and Hailey Baldwin stole the show at separate weddings over the weekend, though they're not necessarily the brides. The 27-year-old pop superstar served as a bridesmaid at best pal Abigail Anderson's wedding, while the 24-year-old model served as the maid of honor at her sister Alaia Baldwin's wedding.

Taylor lent a helping hand as her longtime friend wed photographer Matt Lucier in Martha's Vineyard, Massachusetts on Saturday, September 2. The "Look What You Made Me Do" songstress was stunning in a red long gown with a classic sweetheart neckline and a soft A-line skirt. She was seen carrying Abigail's train as they entered Old Whaling Church in Edgartown.

"She looked gorgeous," one local on the scene told PEOPLE. "She had dark red lips, and carried her friend's train as they went into the church. Security asked the crowd not to rush her." Abigail donned a light pink and white gown.

A group of people gathered outside the church hoping to catch a glimpse of Taylor. They were disappointed when the star hid as she left the church. Security shielded her with large black tarps while she walked from the church to an awaiting SUV, which were only 10 feet away.

Fans who were waiting in the rain went from "We love you Taylor" to a chorus of boos. Some even shouted, "Very disappointing, not cool."

Meanwhile at her sister Alaia's wedding, Hailey looked elegant in a sleek, black halter gown. Alaia, the eldest child of Stephen Baldwin, tied the knot with her boyfriend Andrew Aronow in New York on Saturday.

Her cousin and the eldest daughter of Alec Baldwin, Ireland Baldwin, served as a bridesmaid. She also looked pretty in a black lace, off-the-shoulder gown. The bride wore a white, strapless ruffled, tulle wedding ball gown and later changed into a white sheath gown with tulle cap sleeves for the reception.

I love you guys so much
