Margaret Qualley and Jack Antonoff

The 'Once Upon a Time in Hollywood' actress, 29, married the 39-year-old musician in August after two years together.

The star-studded bash took place in New Jersey and was attended by Taylor Swift, Lana Del Rey, Cara Delevingne, Channing Tatum, and Zoe Kravitz.

Margaret was seen holding hands with her new husband and later arrived at a post-wedding party in a simple white dress while Jack sported a traditional black suit and tie for the occasion.
