The news of Portwood鈥檚 pregnancy came as somewhat of a surprise: During the previous season of Teen Mom OG, she told an MTV producer that the medication for her borderline personality disorder and bipolar disorder restricted her from having a healthy pregnancy. But the reality TV star and author recently told Us Weekly that she鈥檚 successfully transitioned off her medication and is living happily and healthily.

The news follows a tumultuous few years with ex-fianc茅 Matt Baier. It was during a stint on Marriage Boot Camp with her ex that Portwood met her new love. She also shares daughter Leah, 8, with ex Gary Shirley, with whom she currently has a strong co-parenting relationship after a few rocky years. Congrats to the growing family!
