Williams and Lasichanh, who wed in October 2013, are already parents to 8-year-old son Rocket Ayer.

The duo broke the news that they were expecting again in September 2016 when Lasichanh, 36, showed off her baby bump at a Chanel-hosted dinner to celebrate their new fragrance N°5 L’EAU. However, they did not share that three new additions would be joining their family.

Lasichanh, a model and designer, and Williams, 43, were together for years before tying the knot.

“It’s awesome,” the Voice coach previously told Savannah Guthrie of his relationship with Lasichanh. “The bestie thing is awesome. Every night is like a sleepover.”

In a sit-down interview with Oprah in 2014, Williams explained the meaning behind his first child’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 explained.
