Chris Lane and Lauren Bushnell Lane are officially parents of two!

The country music star, 37, and the Bachelor alum, 32, have welcomed their second son, Baker Weston Lane, the couple announced on Instagram Tuesday.

The baby boy was born Sunday, Oct. 16 in Nashville, Tennessee. Bushnell Lane underwent a c-section after her son, who was breech, failed to turn during the final weeks of her pregnancy.

"Life just got 8 Pounds Sweeter! Family of 4 Now!!" Lane captioned a family photo before commenting, "Bigggg bro loves his lil bro! Love our family and proud of you sweetheart!"

The new addition joins older brother Dutton Walker, 16 months, who was pictured meeting his new sibling for the first time on Tuesday in a video the family shared.

"That's your brother!" Lane said to Dutton, who wore a "big bro" tee, as they walked into the room. "Mama missed you bud!" Bushnell Lane told her elder son as her dad David took video. "Look at your brother," Lane told Dutton as he lifted him onto the bed to cuddle with his mom.

Bushnell Lane told PEOPLE that her second pregnancy was a surprise for the couple.

"To be quite honest, I've never been more shocked in my entire life, because this was very much an unexpected surprise," the Bachelor alumna told PEOPLE in June, revealing she interrupted Lane as he put Dutton down for a nap in her rush to show him the positive pregnancy test earlier this year.

"We had planned on having at least two kids, so we're very thankful that it was able to happen for us, even if it wasn't necessarily on our exact timing. We're both just incredibly excited."
