One thing they do have in common though, is that they all became parents before they hit their 20s and fight daily battles involving childcare, work and keeping up with their friends.
Teen Mom UK kicks off next month and here is a sneak peek at the new cast.
Megan Salmon Ferarri, mum at 17
Megan is mum to son Mckenzie and her role model is Beyoncé, because she is an 'independent woman'. She can cook a mean Sunday dinner and would love to open her own restaurant one day. Recalling the moment she discovered she was pregnant, Megan says: "I didn't have a clue what I was letting myself in for."
Amber Butler, mum at 17
Amber believes that becoming a mum to baby son Brooklyn has changed her life for the better. She feels more responsible, reliable and mature and prides herself on working hard. She found telling her family about her pregnancy difficult, saying: "There's never a good time to tell your mum..."
Chloe Patton, mum at 17
Chloe and her boyfriend Jordan hadn't planned to have a baby in their teens, however they couldn't imagine not having son Marley in their lives. Chloe has ambitions of becoming an actress and travelling the world, adding that her dreams have just been "put on hold".
Naomi Konickova, mum at 17
Qualified make-up artist Naomi spends her days juggling nappy changes with creating make-up tutorials. She is mum to daughter Kyanna and loves nothing more than watching her reach milestones. Naomi's mum was not impressed when she revealed she was pregnant: "She took off her shoe and whacked the both of us!"
Mia Boardman, mum at 19
Mia wanted to give her daughter a name no one had ever heard of, so she opted for Marliya. She has an A* in English and hopes to make it as a singer. But recalling her pregnancy, Mia admits she found it tough: "My legs got fat, my ears, my nose, everything got fat. So that was great..."
