These fixer uppers just expanded their home, fivefold!

On Saturday (June 23), Joanna and Chip Gaines welcomed their fifth addition to their family, a baby boy named Crew Gaines. The delivery comes just five months after the reality star couple announced their pregnancy news back in January, in which the twosome revealed their expectancy with a hilarious baby bump reveal.

Blessed beyond belief, the 43-year-old celebrated his son's arrival on Twitter Saturday morning, writing: “And then there were 5.. The Gaines crew is now 1 stronger! 10 beautiful toes and 10 beautiful fingers all accounted for, and big momma is doing great!"

In the hours after giving birth to her bundle of joy, Joanna shared the first-ever photos of the infant on Instagram. "Our baby boy, Crew Gaines, is here and we couldn’t be more in love," the home-renovation guru captioned a set of pics of her cradling the newborn inside her hospital room surrounded by loved ones. "He made an unexpected (and speedy) entrance into the world two and a half weeks early - which is fitting given he was a sweet surprise from day one. Thank you for all your thoughts and prayers. We are so grateful."

Little Crew is accompanied by a long line of siblings — Emmie Kay, 8, Duke, 9, Ella, 11, and Drake, 13 — who were anxious to meet their baby brother, as seen in another adorable shot of the brood waiting outside their mommy's hospital flat.

Last September, the HGTV stars stated they would be discontinuing their hit show Fixer Upper in order to focus on business and their growing family.

"The most important thing in the world is Jo and I's relationship, followed very quickly by these four beautiful kids [of ours]," Chip explained of their choice to cancel the show during an appearance on Today. "We didn't want to push it, redline it for so long that we woke up and realized we are at a point of no return," he continued. "So we wanted to take a step back and focus on what is absolutely the most important thing to us."
