These days, "teen mom" is synonymous with MTV, baby daddy drama, and, unfortunately, rehab. The reality show has come under fire for its supposed glamorization of teen motherhood with stars like Jenelle Evans, Maci Bookout, and Leah Messer Calvert becoming larger than life celebrities whose stories sell tabloids and, thus, ads.

But it wasn't always like that. Obviously teen motherhood is a tale as old as time, but you might be surprised to learn that these 5 well-known and highly successful women were also teen moms. The MTV cast should take note -- these ladies set a wonderful example.
