VIDEO Catelynn Lowell and Tyler Baltierra reveal wedding details

Catelynn Lowell and Tyler Baltierra made their 16 & Pregnant debut over 3 years ago (can you believe it?!), and since then, fans have continued to follow their journey through 3 1/2 seasons of Teen Mom, which is just a few weeks away from wrapping up its fourth and final season. Now that they are done filming their reality show, they are on to bigger and better things — including their upcoming wedding!

“When I found my dress I just started bawling and knew it was it,” Catelynn tells Us Weekly. The Teen Mom couple has already set the date for the wedding next summer. Mark your calendars for July 13, 2013. The date has some significance for the couple — it is just two days before the anniversary of their very first date.

Although setting the date was a bit challenging, it was nothing compared to finding the perfect location. “I wanted to get married in a castle,” Tyler explains. “It’s different and unique. But Catelynn wanted a traditional church thing.” In the end, the pair found Olde World Canterbury Village, a 21-acre historical landmark in Lake Orion, Michigan. There is a castle on the grounds as well as an old barn they transformed into a chapel. Catelynn and Tyler will exchange their personally written vows in the chapel, then as Catelynn explains, “everyone can literally walk from the chapel to our reception!”

As for the guest list, Catelynn and Tyler would both be thrilled if their adopted daughter, Carly, could be a part of the ceremony. They credit Carly with solidifying their relationship and say if it wasn’t for her, they likely wouldn’t even be getting married. Catelynn also says she is inviting all of her Teen Mom co-stars — even Amber Portwood.

The MTV camera crew will also be there, but Catelynn says she still isn’t sure if they’ll film the ceremony or not. “I’m hoping maybe that they will, but if not, I’m going to get somebody to do it.” Catelynn and Tyler love and appreciate all their fans, so they intend to do whatever they have to do to make sure they can share their special day with them.

Once they are married, the couple won’t be in any sort of rush to start a family. They want to focus on their careers and find stability and success before having children. Sounds like a smart plan.
