Matt Dallas, the former star of ABC Family's Kyle XY, has announced he's engaged, marking the first time the actor has publicly discussed he's gay.

The 30-year-old Dallas quietly announced he's taken in a tweet to followers.

“Starting off the year with a new fiance, Blue Hamilton. A great way to kick off 2013!” Dallas messaged along with a photo of himself and a dog lounging on a couch.

Hamilton is a 25-year-old record producer who has worked with Justin Bieber, according to The Hollywood Reporter. He was born in Georgia.

After Kyle XY ended in 2009, Dallas, an Arizona native, was cast to play Roxie's (played by Rebecca Romijn) love interest, Chad, on Eastwick. ABC in 2009 canceled the series after one season.

In 2012, he appeared in three movies: The First Ride of Wyatt Earp, The Ghost of Goodnight Lane, and Naughty or Nice, a made-for-television Christmas movie.

Dallas follows in the footsteps of Sam Champion, the weather anchor for ABC's Good Morning America, who announced he's gay through his engagement to now-husband Rubem Robierb.
