Harry Shum Jr. has got engaged.

The 'Glee' star - who plays Mike Chang in the teen drama - is set to tie the knot with his long-term girlfriend Shelby Rabara after he popped the question back in October while on vacation in Hawaii, his representative told Us Magazine.

The 31-year-old actor and his beau - who starred opposite each other in several episodes of 'Glee' between 2009 and 2010 - reportedly moved in together last month after they purchased a three-bedroom house in Los Angeles in January.

A source said: ''They [Harry and Shelby] have been together for years and are so great together.''

It appears Harry and isn't the only member of the US musical show that is beginning to settle down as his co-star Naya Rivera, who plays lesbian cheerleader Santana Lopez, announced last year she was planning to wed her boyfriend Big Sean.

Meanwhile, Matthew Morrison - who plays teacher Will Schuester - is also heading for the aisle, but not for another year, after he proposed to his partner Renee Puente last June.

He said previously: ''It's [the wedding] is going good. We're a little way off. Probably not until like 2015, so we're just taking our time. But we're well into it.''
