There's nothing stronger than a mother-daughter's bond.

Ever since Mackenzie McKee and Angie Douthit first appeared on MTV's 16 and Pregnant, fans knew that that the pair had a very special relationship.

It only grew as Mackenzie landed on Teen Mom 3 and most recently Teen Mom OG. As she documented her life in front of MTV cameras, however, the proud mom couldn't help but open up about her own mother's health struggles.

And unfortunately, Angie's long battle with brain cancer came to an end this week.

"Momma @angiedouthit has crossed the finish line. She did not lose the battle, she one. She is healed and running in heaven in eternity. Idk anyone who left earth with such an impact," Mackenzie shared on Instagram early Tuesday morning. "Your entire life you never waisted a chance to let the world know Gods love. When we would try to brag on what an amazing person you are you would respond with, ‘It's not me, it's God.'"

She added, "Could you imagine this world if we all lived like Angie Douthit?"

Shortly after the news was revealed, her co-stars took to Instagram and shared well wishes.

"Sending my love and deepest condolences to Mackenzie on her loss…my heart goes out to her entire family," Amber Portwood wrote on Instagram. Maci Bookout added, "An angel has gained its wings."

Take a look back at just some of Mackenzie's heartfelt words and special moments with her mom over the years in our gallery below.
