Catelynn Lowell And Tyler Baltierra Celebrate A Milestone Anniversary

The 'Teen Mom OG' lovebirds shared some very sweet messages to commemorate the occasion.

Catelynn Lowell and Tyler Baltierra have certainly had a momentous 2015: Their beautiful baby girl entered the family fold on New Year's Day (what a way to start the year), and the couple will tie the knot next month in a Renaissance masquerade-theme affair. And today (July 15), the couple is celebrating yet another special occasion: Their 10-year anniversary. They say tin and aluminum are the traditional gifts for this rodeo, C and T!

Naturally, the future Mr. and Mrs. took to Instagram to commemorate a loving decade together -- and the touching messages are guaranteed to make anyone who has followed their MTV journey melt into a sentimental puddle of mush.

"Wow today marks 10 YEARS! With my amazing man!" Novalee's mom wrote along with the throwback photo (such babies!) featured above. "I'm SO blessed to have you! Thank you so much for all that you do and for being an amazing daddy! My life would be so dull without you in it... I love you with every ounce of me! Looking forward to the next 10 years and next month you will be my husband!!! xoxo love you to the moon and back!"

Meanwhile, Ty couldn't help but gush (along with the grinning image below) about his "beautiful soul" and the fact that he has "2 beautiful daughters & an amazing woman to share the rest of my life."

"From the age of 13 years old we literally grew up together," the doting dad began. "We survived with each other, we conquered chaos with each other, & I loved every second of every minute! We got lucky finding each other so young & I can't wait to make you my wife next month @catelynnmtv & spend the next 10 years loving you, caring for you, supporting you, & reminding you every day that you are special, your are beautiful, & as long as I am alive, you will never be alone. Thank you babe for making me the luckiest guy in the world to be wrapped by the wings of a pure angel like yours #LoveThisGirl #Happy10Years #HappyDecade."

Happy 10 years, Tylynn! Share your anniversary wishes for the longtime lovebirds in the comments -- and for a sentimental rewind, relive the moment when Tyler asked Catelynn to be his wife.
