Less than a week after giving birth, Kelly Rowland has revealed the first photo of her son Titan Jewell. The new mom shared the Instagram pic, which shows the back of her newborn’s head. She has also penned a heartwarming lullaby for her bundle of joy called “Mommy’s Little Baby,” produced by Verse Simmonds and The Order.

“I’ve waited all my life, all my life to see ya / I’ve been dreamin’ about you / I wondered what you’d be like / Now I’m speechless,” sings Kelly on the tender tune.

Titan is the first child for Kelly and her manager Tim Witherspoon. The baby boy was born at 1:30 p.m. PST on Tuesday (Nov. 4) and weighed 7.5 lbs.

Beyoncé and Solange congratulated Kelly on the birth of her son, as did fellow mom Ciara. “You are truly a beautiful woman inside and out!” said the “Body Party” singer. “I know you will be the most amazing MOM ever!!”
