On Friday, Oct. 27, "Arrow" actor Colton Haynes married the man of his life, Jeff Leatham, at a Palm Springs hotel. The two had been engaged for seven months.

The 29-year-old "Teen Wolf" star wed Leatham, a florist and Four Seasons artistic director, in a ceremony attended by A-list stars and which was officiated by none other than the matriarch of the popular reality family, Kris Jenner.

Haynes, in an interview with People, revealed how Leatham had helped him improve his relationship with his family and friends. "When you learn to really love someone, it's completely life-changing," he added. Leatham also revealed that the get-together of friends and family for the milestone was far more important than the decorations.

Invited guests heeded the black and white theme of the ceremony. The star-studded event saw Haynes' costar Dylan O'Brien, husband and wife Joe Manganiello and Sofia Vergara, "Working Girl" star Melanie Griffith, and "Modern Family's" Jessie Tyler Ferguson.

Haynes had shared in February this year the proof that he was dating Leatham. His Instagram post showed him and Leatham hugging at the midst of rose petals formed to a heart shape at a rooftop with the sunset as the backdrop. Haynes also reminded people to "never be afraid to love harder" with the caption.

After a month, the 46-year-old creative soul popped the question to the actor at Cabo San Lucas in Mexico. The proposal was witnessed by some of the closest friends in the industry and family members. The rep of Haynes divulged that the two danced to Bruno Mars' "Marry You" after Haynes finally said, "Yes."

Haynes came out in 2016 after a Tumblr post garnered a comment from a fan denoting that he had a "secret gay past," to which the actor replied publicly with, "Was it ever a secret?" It had since stirred controversy.
