True story: we're in love with Mackenzie Douthit's beautiful daughter, Jaxie Taylor McKee. This Teen Mom 2 star gave birth to her bundle of joy three weeks early on February 7, and lil' Jaxie came in at a whopping 8 pounds, 9 ounces. Mackenzie is over-the-moon with happiness about the new addition to her family, which is hardly a surprise — she says that Jaxie saved her marriage to her husband, Josh McKee!

Despite the fact that Mackenzie's labor and delivery was somewhat dramatic (Jaxie was delivered via C-section a few days after Mackenzie suffered an unexpected blood sugar dip), her first night with her husband and baby girl was nothing short of perfection.

"Last night was just too perfect...." she tweeted on February 8. "I'm so in love with my husband and kids."

Considering that Mackenzie recently revealed that she and Josh almost got divorced shortly after their marriage, we're extremely relieved to hear that the whole family is doing so well. We have a feeling this foursome will live happily ever after, and that Mackenzie and Josh's son, Gannon, will be an absolutely stellar big brother.
