Congratulations are in order for Pharrell Williams, he and his wife Helen Lasichanh are expecting their second child.

The couple's rep confirmed the news to E! after a source told the website they have "been wanting another child for a while."

Pharrell and Helen had their first child, Rocket Man, in 2008 and then tied the knot in October 2013.

The pair popped up at the Chanel's No 5 L'Eau fragrance celebration last night where Helen showed off her growing baby bump.

We're delighted for them!
