Pharrell Williams to become a father for the second time

A source told E! News: "They've been wanting another child for a while."

Rumours began to spread when Helen sported the beginnings of a baby bump at Chanel's No 5 L'Eau fragrance party in Los Angeles on Thursday (22.09.16).

Meanwhile, the 43-year-old music producer previously opened up his family life, revealing he loves spending time in the sea in his hometown of Miami.

Writing a piece to mark World Oceans Day, he shared: "Of all the elements, the one I identify most with is water. I grew up in Virginia Beach. I live in Miami. I love boats and I adore being out in the ocean - it's the best feeling in the world. Sometimes I feel like I live on water. Most of my ideas come to me in the shower and the sea always inspires my work. So you can see why water is a huge inspiration to me. It's important for us to act because the ocean is what we all live off - it's our everything and we cannot afford to hurt it."

Meanwhile, Pharrell also previously opened up about why him and Helen chose to name their son Rocket.

He said: "In the same way the Indians named their children after a force or animal or element, we named him after a man-made machine that was meant to go up, meant to ascend."
