Catelynn Lowell and Tyler Baltierra's Wedding: See Her Dress!

It’s a wedding that’s been a decade in the making! Teen Mom OG stars Catelynn Lowell and Tyler Baltierra, who have been dating since they were in seventh grade, finally married on Saturday, Aug. 22, in Charlevoix, Mich., and Us Weekly has the exclusive look at their wedding photos in the latest issue.

The couple, both 23, said their “I do’s” in front of 154 guests on the beautiful grounds of Castle Farms, which features a French Renaissance-style castle. Lowell wore a head-to-toe lace wedding gown with straps, and Baltierra was dressed in a classic tux for their formal, non-denominational wedding.

Fellow Teen Mom OG stars Maci Bookout and Amber Portwood attended with their significant others, as did Teen Mom 2’s Kailyn Lowry.

But perhaps the most important guest of all was their first daughter, Carly, 6, whom the young couple placed for adoption immediately after her birth in 2009. The little girl’s adoptive parents, Brandon and Teresa Davis, who have appeared on Teen Mom OG, were also on hand for the celebration.

Though Carly was a part of the festivities, their second daughter, 8-month-old Nova Reign, had the honor of being the flower girl, and was pulled down the aisle in a white wagon.

With both of their daughters present, it was truly a memorable wedding and beautiful start to Lowell and Baltierra’s new life as a married couple.

“There is no one else I would rather be than [Lowell’s] husband and the father of her children,” Baltierra tells Us. “I’m so honored and blessed to be able to grow old with her.”
