And baby makes seven! Fixer Upper star Joanna Gaines has welcomed her fifth child with husband Chip Gaines, a healthy baby boy named Crew Gaines.

"Our baby boy, Crew Gaines, is here and we couldn’t be more in love," Joanna, 40, wrote on Instagram. "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."

With a couple of kids already in the mix, baby Crew is number five, making the Waco, TX natives a family of seven. Joanna followed up her baby announcement with a picture of the rest of her children — Drake, Ella Rose, Duke, and Emmie Kay — hanging outside the hospital door, waiting for little Crew to arrive. "One of my favorite pics a friend showed me after Crew was born," Joanna wrote on Instagram. "They couldn't wait to meet their new baby brother."

The couple, known for their remodeling TV series on HGTV, has been married for over 15 years and started their family back in the mid-2000s with the birth of their first son, Drake. And while Chip and Jo's name choices for their children have always interested the general public and fans of their show, it's baby Crew's moniker that really has people fascinated.
