Teen Mom 3's Mackenzie Douthit to Become an Aunt!

Teen Mom 3's Mackenzie Douthit is welcoming another baby into her life! No, girlfriend is not pregnant again (as if), but her sister has an adorable bun in the oven, and her baby bump is on full display in this photo from Mackenzie's instagram!

"We're moving on to an awesome," Mackenzie posted along with the picture. "Look at my sisters pregnant belly :)"

Mackenzie has two sisters named Kaylee and Whitney, and though it's hard to tell which one is pregnant, we're putting our money on Kaylee. This gal got married about two weeks after Mackenzie's son, Gannon, was born, so it's about time she pops out a baby of her own, right y'all?

There's no doubt that Mackenzie will be the best aunt ever, and it's great that Gannon will have a playmate so close to his age! Congrats to you and your family, Mackenzie!
