Leah's memorable time on Teen Mom 2 has included her co-parenting with her ex-husband, Corey, and falling in love again and marrying Jeremy.

Viewers have seen Leah face many tough times, from her daughter Ali's health struggles to Leah and Jeremy's divorce. While Leah has been a staple on the show since the start, she hasn't had quite as much drama as some of the other cast members, so she's ranked last.

When news broke that Sarah Palin's daughter would be appearing on Teen Mom OG, she immediately became one of the most memorable cast members thanks to her fame.

Bristol is a great mother whose storyline revolved around raising her three children and dealing with her exes Levi and Dakota. But while everyone knew who she was prior to her time on the MTV reality show, Bristol's time on the series was brief and it didn't stand out too much.

Chelsea DeBoer

Chelsea's time on Teen Mom 2 has been memorable thanks to her love story with Cole. The two are very sweet together and their storylines have been positive, as fans saw them get engaged, get married, have their daughter Layne, and keep building their life.

Chelsea is ranked lower than some of her co-stars as she doesn't bring quite as much drama to the table, and while that's a good thing in real life, reality TV does ask for that kind of entertainment.
