Ace Young and Diana Degarmo attend the 20th Annual Movieguide Faith & Values Awards Gala at Universal Hilton Hotel on February 10, 2012 in Universal City, California.

Unlike most reality show romances, this one’s got staying power.

In April, American Idol alumna Diana DeGarmo opened  up to Yahoo Music about her longterm romance with fellow former  contestant Ace Young, who placed seventh in Season 5.

The pair first crossed paths when they appeared together in a 2010 revival of Hair on Broadway, and quickly bonded over their experience on the  reality show.

“We played with the idea [of dating] when we first met,” DeGarmo shared.  “[But] we were friends, first and foremost..We had both been through ‘Idol,’  which is such a unique and life-changing experience, and we just truly  bonded.”

To couch it in Idol terms, they didn’t, “go through to Hollywood [right  away],” DeGarmo, 24, joked. But now? Gushed the star, “We are best friends! I  truly believe us having been through ‘Idol’ is one of the big reasons as to why  we understand each other so well; unless you go through it, you don’t get  it.”

Given their shared Idol history, the reality show stage served as  the perfect setting for Young to make it official with his love. In a  scene-stealing moment during American Idol‘s Wednesday finale, the  crooner got down on one knee and proposed to the season three runner-up.

“This has always been home to us and I felt that this would be the perfect  place to ask a simple question,” Young told a shocked, and tearful, DeGarmo. “We  have conquered Broadway together. We have created our new music together. We  have an amazing group of people around us. . .I love you to death. You’re my  best friend. I want to make this last forever. . . Diana Nicole DeGarmo, will  you marry me?”
