Shortly after getting engaged to now-husband Jeremy Calvert in late 2011, Teen Mom 2's Leah Messer took the plunge and slapped some corrective metal on her mouth. And in just a few weeks, her new and improved pearly whites will be ready to make their highly-anticipated debut.

"OMG, soooo excited to get my braces off!!! March 12th can't come any sooner!!" the 20-year-old MTV starlet tweeted on Feb. 21.

But that's not the only change in Leah's life. On Feb. 4, she reportedly welcomed her third child (first with Jeremy), a little girl named Addalynn. Between all the breastfeeding and diaper changing — not to mention chasing after her 3-year-old twins Ali and Aleeah! — this new mom is going to have her hands full. Thankfully, crooked teeth will be one less thing to worry about!
