It's a baby boy for singer Karen O and her director husband Barnaby Clay!

The Yeah Yeah Yeahs frontwoman announced the birth of her first child on Instagram with a sweet black-and-white photo of the infant lounging in her arms.

“Shortly after we brought him home I held him in my arms and listened to Roberta Flack singing ['First Time I Ever Saw Your Face'],” she captioned the pic. “I felt my heart exploding in my chest with a love I couldn’t begin to put into words so Roberta’s will have to do for now.”

The new parents in 2014.

The 36-year-old has yet to release the newborn's name and exact birth date, perhaps preferring to keep the details private like she did with her secret wedding to Barnaby in 2011.

Congrats to the new family-of-three!
