Karen O Welcomes A Baby Boy & Shares An Emotional, Yet Adorable, First Picture Of Her Son — PHOTO

Here's some happy news for the lead singer of the Yeah Yeah Yeahs. Karen O welcomed a baby boy with her husband Barnaby Clay, the singer announced on Sunday via Instagram. She shared an adorable photo of her son (she did not reveal his name), along with quite an emotional caption that will make anyone's heart melt. Check it out:

Shortly after we brought him home I held him in my arms and listened to Roberta Flack singing this tune 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 first time ever I saw your face I thought the sun rose in your eyes And the moon and the stars were the gifts you gave To the dark and the endless skies, my love To the dark and the endless skies.

The Robert Flack song O refers to is "First Time I Ever Saw Your Face," which sounds like the perfect track to listen to after welcoming a child into the world.

O never officially announced her pregnancy with a statement, but, in April, she did walk the 30th Annual Rock and Roll Hall of Fame Induction red carpet sporting a baby bump. Why give a statement when you can tell the world you're expecting by showing rather than telling?

Congrats to O and her husband on their adorable new addition!
