Miranda Lambert is enjoying the biggest hit of her career to date right now as "The House That Built Me," spends its third week at #1 on the U.S. Mediabase and Billboard Country Singles charts. In Canada, the song sits on the doorstep of #1 just behind Brad Paisley's "Water."

Miranda's career has skyrocketed this year and she shared what it feels like backstage at the CMA Music Festival. "This year's been really, really huge for me overall and we're halfway through, so it's looking good for the other half! But, you know, I get to be here this year with two #1's under my belt. It's a whole 'nother world for me, it really is. We've done it in a slow, steady build in my whole career but it's, like, all of a sudden we just feel, like... our whole organization just feels this really big push - like we're going to another level - and it's awesome. It's exciting."
