Emma Roberts exchanged vows with Cody John at a private estate in Sun Valley, Idaho, on Saturday.

The ceremony was attended by a constellation of celebrities, including Roberts' aunt Julia Roberts and her husband Danny Moder. Also present were actors Demi Moore, Kristen Stewart and her partner Dylan Meyer, and Ashley Benson with her husband Brandon Davis.

Several of Roberts’ "American Horror Story" co-stars were in attendance, notably Sarah Paulson, who wore a vibrant hot pink dress, and Billie Lourd, who sported a red and white gingham pattern. Demi Moore was seen in a lavender silk dress, while Ashley Benson wore a plum-colored halter gown.

Roberts walked down the aisle with her son, Rhodes, whom she welcomed in December 2020 with ex-boyfriend Garrett Hedlund. Her sisters, Brit and Kara Elkin, served as bridesmaids.

The bride wore a custom Monique Lhuillier gown for the ceremony and changed into another archival Lhuillier dress for the after-party.

A source reported that the wedding took place amidst 95-degree weather and lasted approximately 45 minutes, with guests using white umbrellas to shield themselves from the sun.

Roberts, 35, and John, 36, announced their engagement in July 2024, with Roberts sharing the news on Instagram and showcasing a large diamond ring. The couple were first linked romantically in August 2022. A source told People at the time that Roberts was taking things slow with John, a musician, for the sake of her son. "Emma loves Cody’s personality," the source said. "He’s really funny, and they have been having a good time together."
