They’ve made it to the end zone: Eric and Jessie James Decker‘s baby boy is here!

The country singer has welcomed her second child with the New York Jets wide receiver, the couple announced Friday, sharing his name, photo and details on Sunday.

Born Thursday, Sept. 3 in Castle Rock, Colorado, Eric Thomas Decker ll weighed in at 9 lbs. and measured 20¼ inches long.

“We are so overwhelmed with love and feeling so blessed to have him join our family,” James Decker captioned a photo of her newborn dressed in football gear like dad.

The new addition joins big sister Vivianne Rose, 17 months.

“Thanks for all well wishes! Mama and baby boy are doing great,” Decker tweeted. “Vivi is the sweetest big sister!”

Added James Decker on Saturday, “Thanks for all the sweet messages. Been enjoying my sweet baby boy. He’s amazing. I’m so in love.”

Shortly after debuting her bikini line, James Decker, 27, revealed another big project in the works: a second pregnancy!

When Viv got to meet her lil bro for the first time

“Vivianne is so excited … We are over the moon about having another baby,” the mom-to-be captioned a family photo in March.

Despite their decision to keep the sex of their baby under wraps for a while, the “Lights Down Low” singer couldn’t help but drop a few hints about her “completely different” pregnancy.

“The first time I threw up every day, I was really sick, really exhausted. This one, I have more energy and I don’t feel as sick, no cravings,” she told PEOPLE in April. “The only way I really know I’m pregnant is I feel this bump growing and a baby moving around.”

The secret didn’t last long: Days later, the couple posted a short video clip confirming they were expecting a son. Switching gears from all-things girly didn’t faze James Decker, who already had a name picked out and immediately went to work on a sports-themed nursery.

“We already knew the names before we even knew the sex of the baby,” she told PEOPLE in May.

I don't have much to say

Looking ahead to life as a family of four, James Decker told American Baby she was most looking forward to spending the first few months bonding with her new baby — and not worrying about shedding any pregnancy pounds.

“I know some women slim down through nursing, but with Vivianne, my body held on to some extra pounds to make milk, and that was fine,” she said. “I also love all the cuddling during the baby stage, like when a baby snuggles up under your chin.”

She talks like a trucker, rude and classless.

Normally all the comments are how amazing and awesome she is and fantastic! I think that she thinks she is all of those things as well. She posts so many selfies. I find her to be beyond annoying. And no, I am not jealous. Not. One. Bit.

Anonymous, what a terrible thing to say…I read and re-read what she said, and didn’t get the “truck driver” vibe, and they look quite happy. He may know a side of her you will never understand, so you don’t have a clue what makes their marriage click. The only think that bugs me is no name was announce, and since they already knew what they were naming their baby, why not just say what it is? Congratulations to the happy couple and to their daughter, as well!

She ostracized Eric from his family. Google Jessie James Sarah Decker fight, it is absolutely horrible.

Fuzzy Pumpkin- There are always two sides to every story, and from what I just read (my curiosty got the better of me and I googled it), Eric’s family don’t sound like saints, either.

Anyway, congrats to them!
