"Teen Mom 3" star Mackenzie Douthit McKee is now a mother of three.

The reality star gave birth to a boy named Broncs Weston, her rep confirmed to Us Weekly on Wednesday.

She and her husband, Josh McKee, are already parents to son Gannon, 4, and daughter Jaxie, 2.

Mackenzie seemed all too ready to welcome her newest child last week.

"Momma is getting impatient. 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," she captioned an Instagram photo, adding, "my body truly amazes me."

When she announced the news in April that she was pregnant, she and Josh were apparently separated and lived in different houses.

The young couple's relationship has had its fair share of ups and downs. The two welcomed their first child together when Mackenzie was just 16, and had their saga documented on the MTV reality show "16 and Pregnant." Their engagement, and subsequent battles over whether or not Josh, a bull rider, should continue his work in the rodeo, were all filmed for the third installment of "Teen Mom' franchise.

Back in April 2015 the two also made headlines with their volatile breakup, when Mackenzie crashed her car into a ditch while out looking for her husband. A fight ensued, and Josh ended up throwing her ring in the toilet and leaving the home they shared together.

However, the duo seems to have weathered the fierce storm. Last week, she shared a collage of photos of the two of them.

Everyone has been tagging me in the seven day love your spouse challenge and I know how scatter brain I can be so why not just do 7 photos in 1 post πŸ˜‰πŸ˜‰ over six years ago I met this fella at a basketball game and I knew he fell in love with me right then and right there 😘... He found me on MySpace (yes MySpace) and asked me on a date which shortly led to asking me to be his girlfriend. Wow we had no clue what we were getting ourselves into. So young, dumb, and immature. Through all the break ups, make ups, tears, broken hearts, and pure craziness, God and Love is the only way we have made it here. πŸ™ŒπŸΌ but one thing I know is you have my heart and I have yours and I feel right at home when you hold me in your arms. Thank you for all you do for me and the kids and loving me through all this mess. You are the one my πŸ’— belongs to, and I wouldn't want to do life with anyone else πŸ’‹@joshmckee28
