Congratulations are in order for Teen Mom 3 alum Mackenzie McKee!

The 22-year-old took to Twitter on Tuesday, June 27 to announce that she and her husband Josh McKee have made an addition to their family! The McKees went from a family of five to a family of six — because they just welcomed a new puppy into the mix!

"The McKees added to the family today. We are giving a puppy a forever home. Thank goodness it's not another human," she wrote on Twitter.

She also introduced the adorable new pup to her followers and shared a photo of her cuddling with it on the floor.

The news comes just two months after Mac sparked pregnancy rumors just eight months after she gave birth to baby No. 3 — a baby boy named Broncs. She also shares five-year-old son Gannon and three-year-old daughter Jaxie with her hubby. Back in April, fans started speculating that Mac and Josh were expecting their fourth child when she posted an adorable selfie of the couple and it seemed like she was hiding a tiny baby bump.

But it would nearly be impossible for her to be pregnant again because she got her tubes tied last October — and Mac slammed the rumors in the comments section just for good measure.

"This photo was taken last night. I'm at my smallest weight, and for sure not pregnant. I hope I never tell someone who is not pregnant they are pregnant," she wrote in the comments section.

Meanwhile, Mac is still living her best life and focusing on her adorable family, her fitness goals, and her new Body by Mac business — even though she recently revealed that she was skipped over for her former Teen Mom 3 co-star Briana DeJesus as the newest cast member on the upcoming season of Teen Mom 2. She even threw some major shade at Bri and suggested that the only reason why she's on the show is because she's having her second child with her second baby daddy in an interview with Radar Online.

“I hope MTV didn’t choose her over me because I am married and have three kids with the same guy,” Mackenzie said. “The story on different baby daddies is what people are interested in.”
