Chip and Joanna Gaines Welcome Baby No. 5 -- See the First Pics

The couple shared they had welcomed their baby boy by posting a tweet on Saturday.

Then there were seven!

Fixer Upper stars Chip and Joanna Gaines announced the arrival of their fifth child, a son named Crew Gaines, on Saturday.

The home makeover couple proudly shared that the newborn was in good health, even though he arrived more than two weeks early.

“And then there were 5..” tweeted Chip, who revealed the pair were having a boy in March. “The Gaines crew is now 1 stronger! 10 beautiful toes and 10 beautiful fingers all accounted for, and big momma is doing great! #blessedBeyondBelief.”

A couple hours after the initial tweet, Joanna shared the first picture of her new bundle of joy. 

"Our baby boy, Crew Gaines, is here and we couldn’t be more in love. 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," she wrote alongside an Instagram slideshow filled with her family at the hospital. "Thank you for all your thoughts and prayers. We are so grateful."

Former Bachelor and fellow father, Sean Lowe, was one of the first to congratulate the family, responding, “Congrats man!” which prompted a Twitter user to suggest the two should start a fatherhood conference together.

Being a dad is something Chip knows well as the couple are also parents to Emmie Kay, 8, Duke, 9, Ella, 11, and Drake, 13.

In April, Joanna told ET how she was enjoying pregnancy more this time around because her other kids were older now.

"I am having so much [fun] now that my kids are older," she said. "Time goes by so fast, so this was one of those things where I’m trying to cherish every moment, but back then I had four kids [aged] 4 and under. I was right in the thick of it, trying to figure things out, and now I have four older helpers. They are so excited."

Congrats to the Gaines family!
