Lee DeWyze Engaged to Jonna Walsh!

American Idol winner Lee DeWyze is getting ready to head down the aisle! Lee's rep confirmed to OK! that the guitar-playing crooner is engaged to model/actress Jonna Walsh!

The 2010 winner of American Idol and his new fiancée  met last October while shooting a video for his single "Sweet Serendipity."

Jonna was cast on his leading lady in the clip — and sparks flew!

So where did he pop the question? The most magical place on Earth: Disney World!

Jonna is a huge Disney fan and last week the duo was photographed with Minnie Mouse at the Magic Kingdom in Lake Buena Vista, Fla.

Watch sparks fly between Lee and Jonna in the "Sweet Serendipity" music video below!
