Brooke White and her husband Dave Ray have welcomed their second child into the world.

White, an American Idol alum, gave birth to a son named Sonny John Ray on Saturday.

"Happy Sunday!! Look who finally had a baby. We are so pleased to introduce you to our not so little- little man, Sonny John Ray," White, 33, announced on Instagram.

"Pushed him out yesterday 9/3/16 at 7:08PM at a whopping 9 lbs 9 oz and 22 in! He's alert and amazing and already giving us smiles. Couldn't be more obsessed with our butterball! Can't wait for him to meet his big sister. So grateful! More details to come on his birth, but I gotta feed a hungry kid!"

The actress, singer and blogger -- who performs in the indie-pop duo Jack and White -- shares a four-year-old daughter London with Ray, whom she's been married to for 12 years.

"Forgive me as I just kind of lose my mind over these moments in time and figure out how much to share and not share," White captioned a separate Instagram photo of London looking at the newborn on Sunday.

"Let's start with Loo already taking on her big sister role like a pro and teaching her baby bro some of the basic fundamentals of life, like how to give a peace sign. This is going to be fun."

White revealed she was pregnant again in February after a tough experience with secondary infertility and IVF treatments. Despite several difficult months filled with chaos and hormones, White said at the time conceiving was "totally worth" it and she felt "humbled" by her struggle.

White finished American Idol's seventh season in fifth place. David Cook was announced the winner of the competition in Spring 2008, defeating runner-up David Archuleta.
