On Teen Mom, we saw them go through a lot of ups and downs, which seemed to end on a high note when Tyler proposed and Catelynn said yes.
Last year, however, the reality stars appeared on Couples Therapy and Tyler shocked everyone (including Catelynn) when he revealed that he wasn't quite ready to commit to marriage.
Some time has passed since that episode was filmed and everyone is wondering what Catelynn and Tyler are up to now. In an MTV special airing tonight, we get to catch up with Catelynn and Tyler and find out if they ever got married, if they're still engaged or what the status of their relationship is at this point.
If you think you know everything about them just from following their social media accounts--think again!
In this shocking clip from the episode, Tyler confesses that he knew they weren't going to get married before they even started looking at venues. Are they ever going to get married, though?
