'Teen Mom' Alums Catelynn Lowell and Tyler Baltierra Celebrate 12 Years Together -- See the Sweet Pics!

By
Catelynn Lowell and Tyler Baltierra have been through a lot together.
The Teen Mom stars have been a couple for 12 years, and in honor of their anniversary, Baltierra took to Instagram on Sunday with a sweet then-and-now PDA photo split, as well as a beautiful retrospective for his longtime love.
"I can't believe that today marks 12 years together with you @catelynnmtv, babe you literally are the greatest gift this live has given me!" the now-25-year-old captioned the pic. "We were only kids when we fell in love, but we were kids who knew what we wanted out of life & who we wanted to get it with."
"Not a lot of people get that opportunity or blessing at such a young age," Baltierra added. "Even though we were so young, I wish I could go back as far as I could just to love you longer! I am just so happy & honored to be your husband. I love you SO much! #HappyAnniversary #12YearsStrong #SoulMates #MiddleSchoolSweetheart."

On the show, Lowell (who has now taken her husband's name) made the emotional decision to give her first child up for adoption. The couple had their second child, Novalee Reign, in 2015, and officially tied the knot that August.
Sadly, 2017 has not seen all the Teen Mom alums' relationships continue to flourish.
