The hitmaker Pharrell Williams 43, and Helen Lasichanh, 36, welcomed three babies earlier this month.
The couple confirmed the pregnancy last September – with Helen spotted at Chanel's No 5 L'Eau fragrance party in Los Angeles with her bump on full display.
Pharrell and Helen have been married since 2013.
They are already parents to son Rocket, eight.
Pharrell even wrote Despicable Me song, Rocket's Theme, after the little one.
The US star spoke about Rocket's name choice to presenter Oprah Winfrey back in 2014.
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."
Pharrell formerly gushed about his model/designer wife – claiming "everyday is like a sleepover" with her.
