On Thursday, Joanna, 39, revealed that her younger sister, Mary Kay McCall, gave birth to her sixth child.
“My sister had her beautiful baby girl! #motherofsix #butshelooks16,” the interior designer captioned a series of hospital room pics that featured Joanna, Mary, their older sister, Teresa Criswell, and their mom Nan Stevens.
Joanna and Mary recently worked together for the most recent episode of Fixer Upper.
“It’s my all time favorite reveal because we FINALLY get to do a house for my little sister!” Joanna captioned a picture of the two with their husbands, prior to the airing of the show. “They (5 Kids + one on the way) are moving back to Waco after nine years away.”
Congrats to the McCall family!
