Bruno Mars' hit single 'It Will Rain' has encouraged a seven-year-old fan to record his own version and post it on YouTube.
The 'Grenade' singer uploaded a link to the fan's video on his personal Twitter account saying he really enjoyed the track.
He tweeted: "Awesome!! my favorite part is 3:16 ."
The young fan, called JD, leaps behind his piano and gives a big smile to the camera before introducing the song.
