Farrah had Teen Mom's saddest story, her boyfriend having died in an accident two months prior to their daughter Sophia's birth. She later wrote a tell-all novel, My Teenage Dream Ended and made headlines after making a sex tape with porn star James Deen. She scored her own TV special, Being Farrah, in 2014. Three years later, she was axed from Teen Mom OG, allegedly because of her job as an adult entertainer. The reality star filed a $5 million lawsuit against MTV's parent company Viacom for "sex shaming" her porn career and has since dropped the suit after reaching a settlement. Farrah has remained in the spotlight, starring on reality shows such as Ex on The Beach, Celebrity Big Brother and Botched.
