Taylor Swift is still drawing crowds even though her Eras Tour is on pause for the moment.

The singer attended the wedding festivities of Andie MacDowell’s daughter, Margaret Qualley, who married Swift’s frequent collaborator Jack Antonoff over the weekend.

Swift wore a light blue lacy dress with a corseted bodice and wore her long hair down. She also kept the makeup simple, finishing the look with her signature red lip.

The presence of the "Blank Space" singer caused a frenzy Friday night during the rehearsal dinner at a restaurant in New Jersey.

According to the user, she was visiting friends at a nearby beach house around 8:30 in the evening, the crowd outside grew and police had a hard time keeping them contained and keeping the streets open. She added they were chanting "We want Taylor," and described the scene as a "madhouse."

The chaos sparked debate online among Swift’s devotees, some of whom claimed the people gathering at the restaurant were being too intrusive in the singer’s life.

The wedding weekend was a star-studded event, with famous guests including rumored couple Channing Tatum and Zoe Kravitz in attendance, along with singer Lana Del Rey and model Cara Delevigne.

Antonoff has worked with Swift since 2012 and produced on her last six albums, including the most recent, "Midnights."
