It's official: Blake Shelton proposed to Miranda Lambert on Sunday! Miranda reveals to People.com, "He called my dad and got his blessing first. That was so Southern and old-school and perfect." So how did Blake do in picking out her engagement ring? Turns out Shelton did real good, proposing to Lambert in the woods near her Tishomingo, Oklahoma home with a beautiful diamond-and-platinum ring. Miranda gushes, "I was so proud of him. We've been together five years, so he knew exactly what I wanted, but it's so much more perfect than I could have picked out myself." Lambert shares that they celebrated with "a couple of Bacardi and Diet Sprites – in a Solo cup!" Yesterday afternoon, Blake took to Twitter to express his joy, tweeting, "So excited about being engaged to Miranda I tea bagged a meat grinder and golf clubbed a panda bear..." For the full story – as well as a picture of the ring, which Lambert posted a picture of on Twitter – check out the new issue of People on newsstands this Friday.
