What Music Video Is This Picture From?

What an adorable little girl! She is actually a mini-me of the country singer who takes the lead on this song. Big eyes, brown hair -- they depict this artist in childhood, but the question remains: Has she kept her brunette locks as she's risen to fame?

The song's lyrics state a longing for life back when it was more simple, pure and free. Fittingly, the video was filmed in the sunshine and open air -- the perfect playground for kids. Innocence, bike rides and falling in love for the first time are all part of this mystery music video. The song was certified Platinum, despite many negative reviews for the melody, vocals and drumbeat, and the singer(s) just keep getting better, with almost five years of new experience between the song's release and the present. Any guesses?
