Teen Mom 3 star Mackenzie Douthit has given birth to a baby boy.

Douthit, 21, welcomed her third child with husband Josh McKee on Monday and the couple named him Broncs Weston, Us Weekly reported.

Douthit and McKee, a bull rider, wed in a country-themed wedding in August 2013. They are already parents to a four-year-old son Gannon and two-year-old daughter Jaxie.

One week ago, Douthit captioned a photo of her large baby bump on Instagram.

"Momma is getting impatient," she wrote. "I'm so ready to hold baby boy and so blessed with friends and family, at my 35 week appointment he was measuring over 10 pounds. my body truly amazes me."

Douthit, who also starred on an episode of 16 & Pregnant, announced she was expecting Baby No. 3 back in April.

The reality TV star considered Broncs a miracle since she has type 1 diabetes, which posed a threat to her first two pregnancies.

"God has truly blessed us with healthy kids when the doctors once told me my body could never carry one. Although baby number 3 was a huge risk and my body could never carry another, we made it to the end with lots of fear and prayers," Douthit captioned a photo on Instagram one month ago.

Teen Mom 3 wrapped in November 2013. MTV canceled the series after only one season.
