Wedding Funny Moment : Taylor Swift makes raucous 15-minute toast at Jack Antonoff and Margaret Qualley’s wedding

Spies tell Page Six exclusively that Swift, 33, hilariously and lovingly “roasted” the couple during her lengthy toast, and that Del Rey, 38, sang her tune about Qualley, “Margaret.”

We hear that Swift’s speech included a crack about how she always thanks Antonoff, her frequent musical collaborator, in her awards show acceptance speeches — and that he never mentions her in any of his.

The Bleachers frontman has won eight Grammys, including Producer of the Year in 2022 and 2023, while Swift has taken home 12. They met in 2012 and have joined forces on multiple albums, including her 2022 smash, “Midnights.”

Also at the party, we hear that a tattoo artist was on hand to ink permanent memories of the occasion.

Spies say that speakers at the wedding reception also included the bride and groom’s parents, Andie MacDowell, Paul Qualley, and Rick Antonoff and Shira Antonoff and siblings Rainey Qualley, Justin Qualley and Rachel Antonoff, as well as “Brittany Runs a Marathon” filmmaker Paul Downs Colaizzo.

Communications strategist and close friend of the couple Andy Snyder officiated the proceedings, we hear.

Mark Seed — who coordinated Jennifer Lawrence’s 2019 wedding to Cooke Maroney — planned the star-studded event, where A-list guests also included Cara Delevingne, Channing Tatum and Zoë Kravitz, The 1975 drummer George Daniel and “Real Housewives of New York City” star Jenna Lyons.

Del Rey’s “Margaret” features Antonoff’s band Bleachers.

The “Summertime Sadness” singer, who received backlash for wearing white to the nuptials, previously told Rolling Stone in an interview that the song “could hypothetically be played at their wedding.”

Del Rey once said her song “Margaret” could be played at Antonoff and Qualley’s wedding.

Swift also reunited with former “girl squad” member Delevingne, 31, at the ceremony.

We reported that the superstar pals spent three hours inside Shore hotspot Bird & Betty’s, where they danced and watched the newlyweds cut their cake.

Antonoff and Qualley have been a couple since 2021.
