Those are two good-looking pairs of legs that belong to one guy and one gal. But as far as which set of legs belongs to the artist in the music video, we won't tell. We will reveal this, however: the day this video was shot in Nashville, the temperature outside was steamy at 114 degrees, which made it difficult for this artist, who rode a bicycle in a few scenes. Any guesses?

The singer made history with this track as the most-added debut artist in 2012 -- the song was added to the playlists of 55 radio stations, which is extremely impressive for someone so new. Perhaps they had another career that made them an already recognizable public figure ... ? Now that's a big hint. Do you know what music video this picture is from?
