UPDATE: When Chip Gaines tweeted yesterday to say he and his wife Joanna's new baby had arrived and that the Gaines “crew is now one stronger,” perhaps he had carefully chosen those words to tease the boy’s unique name.

Last night, Joanna shared pictures of the family’s newest bundle of joy on Instagram — and revealed that his name is Crew.

“Our baby boy, Crew Gaines, is here and we couldn’t be more in love,” she captioned a series of pictures taken at the hospital. “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.”

The name Crew breaks from Gaines family tradition since their sons Duke, 9, and Drake, 13, are both “D” names. (The girls Emmie, 8, and Ella, 11, also have matching first initials.) Looks like they had trouble coming up with a name that started with a “D,” though — Chip had joked back in March that the only thing he could think of was “Dragon,” which Joanna quickly turned down.

The baby’s name also seems like it could be a sweet nod to the fact that he’s now part of the extremely close family. Joanna posted a picture of the four older kids standing of the hospital room door, looking as though they were eagerly anticipating their new sibling.

“They couldn't wait to meet their new baby brother,” Joanna wrote.

While the couple’s hit HGTV show “Fixer Upper” has concluded, they’re still busy with their many other projects including a new restaurant and upcoming book. But Chip and Joanna have both said that family is their focus.

Congrats to the crew… and Crew!

Chip tweeted the exciting news Saturday morning, writing that the Gaines crew is now stronger by one.

“10 beautiful toes and 10 beautiful fingers all accounted for, and big momma is doing great! #blessedBeyondBelief” he wrote.

The couple — who announced in January they were expecting — are already parents to Drake, 13, Ella, 11, Duke, 9, and Emmie, 8 (and not to mention many animals!)

Chip revealed the baby’s gender back in March during a sweet conversation with his buddy Gage, an 8-year-old boy with a rare genetic disorder. “It’s a little boy and I need a 'D' name,” Chip said, asking the child for his help.

In the video, Chip joked that all he could come up with was “Dragon,” which Joanna shut down quickly. No word yet on what the baby’s name actually is, but we can say with confidence that the Gaineses passed on that one!

The parents seem to be pros at raising kids while juggling their careers. But Chip has said that if there is ever a need with family, he’ll "shut it all down so fast it will make your head spin."

“Jo & I believe, w/ God anything is possible. Including having an amazing family AND career you love,” he tweeted back in April.

While they have a lot going on in their professional lives (a new restaurant, book and home decor line, to name a few), the couple will no longer feel the weight of their hit HGTV show, "Fixer Upper," since the show concluded in the spring.

“Right now what we're focusing on is just family, our businesses here in town and obviously me being a mom to a newborn,” Joanna told TODAY’s Jenna Bush Hager in May.

Congrats to the happy family!
