Oprah Winfrey makes 'I'm so happy!' star - Pharrell Williams cry!

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.’
‘Shower's good, isn't it?’ Oprah says. ‘There's something about the water.’
‘The water attracts your ear,’ he says. ‘You get distracted, and your mind wanders.’

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.'
The interview also saw Pharrell talk about his critically-acclaimed new album ‘G I R L’, and his wedding last year to model and designer Helen Lasichanh.

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.

Big weekend: Pharrell performed at Coachella on Saturday

He brought out Nelly for Hot In Herre, Snoop Dogg for Drop It Like It’s Hot, Gwen Stefani for Hollaback Girl, and Busta Rhymes for Pass The Courvoisier.
Some of the tracks were produced by Williams and Chad Hugo who made up the record production duo The Neptunes.
But Pharrell wasn’t too happy with the dust and wind experienced at Coachella as he told the packed crowd, ‘I wanted this s*** to be so much hotter but the dust and this f***ing wind…,’ according to The Guardian.
