Mackenzie McKee is facing a new chapter of motherhood.
The Teen Mom: The Next Chapter star expecting twins with fiancé Khesanio Hall, she announced on March 31.
"No one knows I'm pregnant, but I am," Mackenzie—who is also mom to kids Gannon, 13, Jaxie, 10, and Broncs, 7, with ex Josh McKee—shared during an appearance on The Drew Barrymore Show. "There's two in there."
Alluding to her past teen pregnancy and her in-vitro fertilization (IVF) journey, both of which were documented on the long-running MTV franchise, the 30-year-old jokingly added, "It was planned—finally!"
The pregnancy news comes nearly a year after Khesanio, 30, popped the question during a romantic beach proposal. At the time, Mackenzie said the soccer player is "100 percent my person."
"When two people come together and they're not compatible, it just doesn't make sense," Mackenzie told E! News in May, noting that their relationship "so far has made a lot of sense."
"There hasn't been one red flag," she continued. "We make a lot of sense together. Just being around each other our very first night, it was like, 'Oh my gosh, this is so compatible.'"
Though she and Khesanio grew up in "two different worlds," Mackenzie said their personalities are actually very similar.
"You have your Oklahoma girl and someone from Jamaica, and then they both end up in Florida," she explained. "Way different lives, but so much alike when we hang out."

Plus, according to Mackenzie, her kids have a formed a bond with Khesanio like no other.
"My kids are raised by Khes, so he is security for all of us," she told People last year. "The hero that came to our rescue. I love his love for them.
The fitness trainer added, "It’s not just a stepdad relationship, it’s a true love deep in his heart. I know my kids wouldn’t want life any other way than for Khes to be a part of it forever."
