Rapper Pharrell Williams’s wife Helen Lasichanh is expecting their second child.

A representative for the “Happy” hitmaker has confirmed that his wife is pregnant, reports aceshowbiz.com.

Williams married Lasichanh in 2013. The couple already has a seven-year-old son named Rocket Ayer Williams. Williams’s song “Rocket’s theme” was written in honour of his son.

In a 2014 interview with Oprah Winfrey, Williams explained his son’s name.

“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,” he said.
