Mark Ronson and Grace Gummer have made their official red carpet appearance as a couple!

The 45-year-old music producer and the 35-year-old Dr. Death actress were in attendance at Gucci and the Saltzman Family’s Summer Celebration event on Saturday (July 10) in East Hampton, N.Y.

The event was held to celebrate the opening of the East Hampton boutique and to mark Gucci’s return to The Hamptons in a permanent capacity. Stylist Elizabeth Saltzman hosted the event at her family home.

Mark performed his first DJ set in over two years and he closed the night with a tribute to Britney Spears by playing her song “Toxic.”

During the event, Mark and Grace, who recently got engaged, mingled with stars like Derek Blasberg and Jeremy O. Harris.

FYI: Mark, Grace, and Jeremy are all wearing Gucci.
