The controversial pair has had their fair share of ups and downs when it comes to getting engaged. On a previous season of Teen Mom, Farrah purchased an engagement ring with the hopes that he would propose, but he never got down on one knee. On a more recent episode, Farrah called it off completely with Simon because he didn't want to get married.

Here's to hoping the two are now in a good place!
