Miranda Lambert: Engaged to Blake Shelton!

Country hotties Blake Shelton and Miranda Lambert are engaged! He popped the question May 9 - and in classy fashion for a self-proclaimed "hillbilly" singer.

"He called my dad and got his blessing first," Lambert told People of her boyfriend of five years. "That was so Southern and old-school and just perfect."

Equally perfect: The diamond-and-platinum ring he picked out.

"I was so proud of him," says Lambert. "He knew exactly what I would've wanted but it's so much more perfect than I could have picked out myself."

The setting for the proposal was distinctly down-home – in the woods near Lambert's Tishomingo, Okla., home, followed by a similarly informal party.

The engagement is yet another high point in a stellar year for Lambert, who in January scored her first No. 1 single with "White Liar" and in April won Album of the Year and Top Female Vocalist at the ACM Awards.

Congratulations to Miranda Lambert and Blake Shelton!
