Lauren Bushnell, Chris Lane Welcome Baby Boy Dutton: See Sweet Video

Lauren Bushnell and Chris Lane are officially parents after they welcomed their first child this week.

The "Bachelor" alum, 31, gave birth to baby boy Dutton Walker Lane in Nashville, Tennessee, Tuesday, the couple confirmed to People.

Bushnell and Lane's son weighed 9 pounds and measured 19.5 inches long when he was born. According to the country singer, they were shocked by the size of their newborn.

"Everyone in the room, including Lauren and me, were shocked we had a 9-pound baby! Not sure where he was hiding in her belly?!" Lane, 36, joked.

"Watching Lauren go through the birthing process - from the beginning to the moment she delivered - was the most incredible thing I've ever witnessed. I experienced an emotion I've never felt before," he continued.

Bushnell shared, "I've never felt an immediate unconditional love like I now have for Dutton. And going through this experience with Chris has made me love and appreciate him even more … I didn't think that was possible!"

Lane wrote his hit song, "Big, Big Plans," for his proposal to Bushnell, and the singer has also penned a song for his son.

"I've been waiting to meet Dutton for nine months now, and the easiest way for me personally to describe my feelings and emotions is to write about it! So naturally, I wrote a song," Lane said.

"It's called 'Ain't Even Met You Yet' and sums up how I've been feeling over the last few months. I can't wait to share it with him one day," he revealed.

Both Bushnell and Lane shared snaps of their baby on their social media accounts. The reality star shared a photo of herself holding her newborn son and another shot of her husband carrying Dutton.

"Dutton Walker Lane born June 8th, 2021. Your dad and I can’t get enough of all 9 pounds of you. Now back to baby cuddles and praising Jesus over and over again for this little miracle!!" she wrote in the caption.

Meanwhile, Lane shared a short video of him sitting while cuddling Dutton. "It's my first time holding him," he said.

"Words can’t describe the love i feel inside my heart for this little man! Thanks for all the prayers I will never understand how @laurenlane birthed a 9 pound baby! DUTTON WALKER LANE welcome to the world," he captioned the clip.
