American Idol's Lee DeWyze: Engaged to Jonna Walsh!

American Idol winner Lee DeWyze and Jonna Walsh are engaged!

The 25-year-old singer popped the question to Jonna, his girlfriend of eight months, over champagne on a private yacht under a fireworks-filled sky at Disney World, according to People.

“Jonna is a Disney freak,” Lee said. “They were playing love songs on the boat and I got down on my knee and asked her. I had a speech prepared but it all went out the window so I just asked her. She started crying and I said, ‘Is that a yes?’”

Lee and Jonna, 26, met on the set of the music video for his single “Sweet Serendipity.” They will be married in the fall of 2012.

Congrats to the happy couple!
