Pharrell Williams cries tears of joy during Oprah Winfrey interview

He may have written the happiest song of the year, but Pharrell Williams was reduced to tears during his interview with Oprah Winfrey.The Happy singer sat down with the talk show host for an upcoming episode of Oprah Prime on her OWN Network, and was moved by a video shown to him of people dancing to his chart-topping song.

‘I'm so happy!’ Pharrell, 41, cried before Winfrey showed some pictures of him as a child

During the interview, Williams – wearing one of his many distinctive Vivienne Westwood hats - discussed his rise to fame, his song-writing process and the music that influenced him to become a seven-time Grammy winning recording artist and producer.

‘My best songs come from two different ways,’ he says. ‘Either when I have a really good gut feeling about something, it's written in the shower or on a plane.’

But for his Despicable Me 2 song, Pharrell called it a ‘crazy, half-court shot.’

‘It's not because you're that good,’ Williams says. ‘It's because you're out of ideas.'

But over the weekend, he was in Indio, California to perform at Coachella 2014, where he reminded the audience of just how many hit songs he’s been behind.
