It’s not easy being a Teen Mom, even when your adolescent pregnancy makes you an MTV star. The cast of Teen Mom OGFarrah Abraham, Maci Bookout, Catelynn Baltierra, and Amber Portwood — have all had heartbreak and hardships. For example, one of them lost her daughter’s father in a car crash, one of them served time behind bars, and more than one has called off an engagement.

Through it all, however, they haven't given up on finding happiness — and we should note, they've had highs to balance the lows. One is currently pregnant with a boy, one has released multiple memoirs, and one even launched a pasta sauce. (Random, we know.) Scroll down to see how all four women have evolved in the years since the reality show’s 2009 premiere.
