Teen Mom's Maci Bookout has changed immensely since giving birth to her son Bentley over four years ago. When we first met the Chattanooga cutie on Season 1 of MTV's 16 and Pregnant in 2009, she rocked pin-straight ginger hair and an adorable baby bump. Nowadays Maci's totally glammed out with a killer closet full of color denim and Chuck Taylors to match.

But what did our girl Maci look like before her fresh face appeared on MTV's hit docu-series? She was just your average sweet Southern girl next door!

On March 20, Maci tweeted a Throwback Thursday picture from vacation in Mexico in 2008. While she doesn't look crazy different in the photo, it's obvious how much she's grown up in the past five years.

These days, the aspiring media maven looks way more polished and professional — even with all those tattoos she's acquired throughout the years. And she's certainly got the résumé to back it up. Not only does she have her own radio show called "Ask Maci," but she's also the official after show host for MTV's Teen Mom 2. She's come a long way!
