"Teen Mom" star Mackenzie McKee had four years worth of photos deleted after a hacker gained control of her Instagram account and wiped it clean.

According to our sources, McKee tried to log in to her profile on Monday but was denied and quickly noticed a hacker changed her profile name, password and deleted her photos.

We’re told the reality star was able to get in contact with people at Instagram, who are working to resolve the issue and get her account back up (hopefully with that coveted blue check mark).

Mackenzie has recently been using her social media accounts to promote her mom's new book, "God’s Plan," with all the proceeds going toward her treatment costs.
