The celebration took place in Palm Springs, CA, and was officiated by none other than Kris Jenner, Kardashian-Jenner matriarch and superstar momager.
Guests included Sofia Vergara, Joe Manganiello, Jesse Tyler Ferguson, and Justin Mikita.
Haynes’ AHS: Cult co-stars, Leslie Grossman and Billie Lourd, also took part in the couple’s special day.
“Thank you @jeffleatham @coltonlhaynes for including us in the most magical night,” Grossman wrote alongside a pic of the three. “Wishing you a lifetime of love and happiness and champagne and dancing and matching sparkly jackets.”
The evening before his big day, Leatham shared a glimpse of the party to come.
“I have the honor and great pleasure of Marrying this Amazing Human Being tomorrow,” he wrote.
“I love him to the moon and back and I am Blessed to soon call him my #Husband – One more sleep baby.”
In March, Haynes announced his engagement to Leatham via Instagram.
“I SAID YES!!! <3 @jeffleatham,” he wrote alongside a striking picture of Leatham and himself kissing next to a personal fireworks show in Cabo San Lucas, Mexico.
Congrats to this beautiful couple!
