MTV will bring us more tearjerking real-life drama in the form of four new teen moms starting Jan. 11 — and now, EW has learned, the network has chosen which 16 and Pregnant subjects will continue to open their complicated lives to TV audiences in Teen Mom 2.

The new cast will be: Chelsea, from Vermillion, S.D., who has a great supporter in her dad but a volatile relationship with her boyfriend; Kailyn, from Nazareth, Pa., who’s living with her boyfriend and his parents; Jenelle, a North Carolina surfer who’s struggled to put her carefree partying days behind her to focus on her newborn; and Leah, a West Virginia cheerleader raising premature twins with her boyfriend. Original Teen Mom participants Amber, Catelynn, Farrah, and Maci are still filming as well and will return to the airwaves in a future season.
