Michelle Duggar welcomed baby No. 19 Thursday -- much earlier than expected.
"Michelle, who has been in the hospital recovering from a gallstone, was taken to the OR for an emergency C-section," a rep for TLC, which airs her reality show "18 Kids and Counting," told TMZ Friday morning.
At 6:27 PM PST, Michelle and her husband, Jim Bob, welcomed their daughter, Josie Brooklyn, who was due in the spring. She weights in at just 1 lb., 6 ozs.
The baby is stable, but was admitted to the Neonatal Intensive Care Unit at the University of Arkansas Hospital for Medical Sciences.

Adds the rep, "The most important thing right now is for Mom and baby Josie to get as much rest as possible. The family is grateful for all the prayers and well wishes during their recovery."
Last weekend, Michelle was airlifted to the hospital when the gallstone pain caused her to have early contractions.
In a message recorded on their iPhone Tuesday, the couple thanked "everyone for praying for Michelle."
