Tyler shared part of the invitation to Instagram which showed it features an image of a fairytale castle and the words: "It is by decree of the lord and lady that the people of the manor are invited to attend the noble marriage of Catelynn Lowell and Tyler Baltierra."
He added: "Wedding invitations are on their way out! I can't wait until August! Catelynn is going to be the most beautiful bride. #10weekstogo."
It's thought the reception will take place at Castle Farms in Charlevoix, Michigan after Tyler also shared an image of the couple at the venue.
Teen Mum fans will be pleased to see the couple get their fairytale ending after watching their relationship grow and strengthen on TV screens.
We met them when they were young teenagers on 16 & Pregnant. Catelynn fell pregnant at a young age and we watched as they made the difficult decision to place daughter Carly for adoption as they felt it was in her best interests.
Their journey continued in Teen Mom, and then the recent Teen Mom OG, where we learned Catelynn was pregnant again. She gave birth to daughter Novalee in January.
Last week, Tyler told fans: "I gotta tell ya, being loved by this woman is a true gift & I am the luckiest man in the world to be able to spend the rest of my life with her #MyBabe #LoveHer."
They shared their story in the recent book, Conquering Chaos.
