Pharrell Williams cries tears of happiness in an upcoming interview.

The singer has had an amazing year so far and was nominated for an Oscar with his it Happy, which appeared in Despicable Me 2. He's also announced several new fashion collaborations, including with brands Adidas and Peace Love World.

In a new interview with talk show queen Oprah Winfrey, the 41-year-old couldn't contain his emotions.

"I'm so happy," he sobs in a preview for the Prime episode, which will air on Oprah's OWN network.

The teary moment was brought on when the chat show host showed him a video of people dancing to his Happy tune.

Last month, Pharrell released his latest album G I R L. Inspiration for his songs often hits him in unlikely places.

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

"The water attracts your ear... You get distracted, and your mind wanders."

The singer is also having a good time in his personal life. He married model-and-designer Helen Lasichanh in October last year and they have five-year-old son Rocket together.

During the preview clip, Pharrell also looks on teary eyed as pictures from his childhood are shown, including an adorable snap of the singer as a young boy, sporting an afro and a double denim outfit.

While Happy is loved by most people, the star's racy track with Robin Thicke, Blurred Lines, was criticised by some for its suggestive lyrics and raunchy video. Despite the raised eyebrows, Pharrell insists he's a feminist.

“Most things one day will lose their value. But women never do. They are unique and individual,” he told British newspaper The Sun.

“I love women and often admire their eyes, lips and other features of their bodies in a sometimes suggestive way.

“But I respect and hold what would be called ‘a feminist view’ too. I want to spread the message of the pertinence of women on this planet. It calls for the equivocation of women in society.”
