Disney alum Garrett Clayton is going public with his engagement.

The 27-year-old actor said in an Instagram post Thursday that boyfriend Blake Knight proposed to him one year ago during a trip to Iceland.

Clayton shared a slideshow of photos with fans, including a picture of Knight on one knee and a snapshot of his engagement ring.

"It's been 1 year since @hrhblakenight asked me to marry him in Iceland on the most beautiful trip and the most beautiful day of my life to date," Clayton captioned the post.

"I'll never forget your face in that moment when you got down on one knee. Love, nervous, and excited (Obv, I was going to say yes) all rolled into the love of my life," he said. "Everyday with you is filled with joy and laughter."

The Teen Beach star said he and Knight will celebrate their eight-year anniversary as a couple in a little over a month. The pair first met while Clayton was working as a waiter at a 24-hour restaurant in Los Angeles.

"I was a waiter aspiring to be an actor. You were an assistant aspiring to be a writer," Clayton recalled. "Now look at us! Living the dream together."

"You've never faltered in being a supportive, loving, stubborn, sensitive rock in my life. Here's to another 100 years of traveling the world, stealing your socks and loving our babies, whether their dog babies or actual babies. I'll love you forever."
