Pharrell Williams and his wife Helen Lasichanh have three new reasons to celebrate!

The "Happy" singer, 43, announced that he and Helen, 36, welcomed triplets in January. The couple's representative told E! News, "The family is healthy and happy."

We don't know the genders or names of the babies yet — but we can't imagine they can keep it a secret for long!

The couple is already parents to Rocket Ayer, 8. In fact, Pharrell wrote the Despicable Me song "Rocket Theme" in honor of his son.

He explained the unique name for his son by telling Oprah, "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."

The couple revealed they were expecting last September when Helen debuted her baby bump at a party hosted by Chanel. While everyone believed they were expecting their second child, they were actually expecting their second, third, and fourth children.

The couple has been together since 2008 and tied the knot in 2013. Pharrell admitted that their relationship wasn't always easy in the beginning.

"I hurt her a lot in the very beginning once she was free and was available, because I had given her all of this attention but I wasn't ready to like, let go [of his life as a bachelor]. I looked at my life and I was like, 'Man, I could keep doing this for another 10 years, is that what I want to do?' And so I made a decision. And then we made a decision and just started dating," he said.

We're so happy everything worked out for them — and we can't wait to see the triplets!
