Musician's father-son duet of Justin Bieber's 'Baby' will make your day

Tom Fletcher and his adorable son Buzz are no strangers to the music world.

Not only is Fletcher the frontman of the British rock band McFly, but his toddler has become a musician-in-training, lending his own adorable vocals to his dad's favorite hits.

A few weeks ago, the father-son duo performed the cutest cover of "Easy" by The Commodores. While Tom may have been carrying a bulk of the leg work, his one-year-old back up singer was the real highlight -- receiving over 120,000 likes on Instagram alone.

After becoming an Internet musical sensation overnight, the pair quickly took to Facebook for their latest rendition. Their newest cover? Justin Bieber's "Baby" -- how fitting?
