Country music's cutest couple often takes to Twitter to express their mutual adoration. Miranda tweeted this photo of her and Blake visiting the San Diego Zoo on Dec. 12, 2012. "We had a blast at the San Diego zoo!!!! Thanks so much. #zoodate," she wrote. But her tweet on Jan. 23, 2013, was much more effusive: "It's official! I have the BEST husband in the world. Girls... don't settle for any less than amazing. I love @blakeshelton to death!"
