Pharrell Williams on popularity surge

As a songwriter and producer, Pharrell Williams has worked with stars from Britney Spears to Kanye West - but recently he has become a global hit himself.

Williams is the man behind some of the catchiest tunes and controversial lyrics of the past year, with songs like 'Happy' and 'Blurred Lines'.

BBC Breakfast's Sally Nugent had a chance to catch up with Pharrell earlier this week.
