Following on from his huge success in 2013 with hits including 'Get Lucky' and 'Blurred Lines', Pharrell Williams has returned with the incredible 'Happy' - one the most catchiest, upbeat tunes we've heard in a long time As much as we love the new song, it's the music video that's caught our attention.
Mr Williams has created the first 24 hour music video capturing people dancing in train stations, petrol stations, pavements (and many more), as well as cameo appearances from Steve Carell, Jimmy Kimmel and Kelly Osbourne. You might even recognise the tune from Despicable Me 2.
So to put an instant smile on your face and have you clapping along all day, watch the official music video below - don't worry it's not the 24 hour version
