What Music Video Is This Picture From?

The beloved guitar and the gorgeous gal holding it are two of the main components of this mystery country music video. Besides the country stars who appear in the clip, she's the only other character featured; there's no guy, no family, not even a dog pictured with her throughout the whole four minutes. It's just her and her guitar. Any guesses?

This song debuted in early 2010 and was the fourth single from this band's record, which streeted in 2008. It has a somber feel, and the character shown above is supposedly based on a legendary queen consort. That's a pretty big hint right there ... do you know what music video this is from?
