The pair, who have been dating since the seventh grade, finally said their "I do's" this weekend at their Renaissance-themed wedding.
Dawn Baker, the adoption counselor they worked with when they placed Carly with Brandon and Teresa, shared this photo of the beautiful bride in her gown:
As if Cate and Ty weren't already total relationship goals, Tyler gave the sweetest comment ever to Us Weekly regarding their nuptials. "I believe Cate was brought into this world and destined to be loved by me, cherished by me, admired by me, and forever cared for by me," he told them. "There is no one else I would rather be than her husband and the father of her children. ... I'm so honored and blessed to be able to grow old with her."
The mag also reports that there were 154 guests in attendance, including Tyler's dad Butch, who was recently released from prison.
Also in attendance was their daughter Carly and her adoptive parents Brandon and Teresa. The couple's second child, Nova, was their flower girl.
Teen Mom co-stars Amber Portwood and Maci Bookout also were present for the special occasion and they each brought along their fiances. Maci shared this gorgeous photo of herself and Amber just before the couple walked down the aisle:
Congrats, Cate and Ty! Wishing you many (more) years of love, laughter and happiness!
