In 2001, Pharrell Williams got his hands on Britney Spears, writing and producing songs like 'I'm A Slave for You' and 'Boys' for the pop princess third studio album Britney. A year later Williams remixed 'Boys' and jumped on the track with Brit. The N.E.R.D. mastermind is having a moment...he is heavily featured on the summer's two hottest singles, 'Blurred Lines' by Robin Thicke and 'Get Lucky' by Daft Punk. So we thought we'd celebrate with this fun pop duet.
