Bristol Palin hasn't been a teen mom in years, but that's not a dealbreaker for MTV.
Variety and TMZreport that Palin, the 27-year-old daughter of former Alaska governor Sarah Palin, is joining the cast of Teen Mom OG this fall. Not long after presidential candidate John McCain announced in 2008 that her mom was his running mate on the Republican ticket, Palin revealed a bombshell of her own: she was pregnant at 17. Palin gave birth to her son, Tripp, that December, and has gone on to have two more children — daughters Sailor Grace, 2, and Atlee Bay, 1. She's also been on several reality shows, including Dancing with the Stars (she came in third) and Bristol Palin: Life's a Tripp (it got canceled after one season).
The other stars of Teen Mom OG appeared on episodes of the show 16 and Pregnant, which chronicled their lives as high school students dealing with pregnancy, childbirth, and the early days of motherhood. Palin has parlayed her experience as a teen mom into several job opportunities, including as the Teen Pregnancy Prevention Ambassador for the Candie's Foundation. Catherine Garcia
