It's a sad time for Mackenzie McKee.
The Teen Mom 3 star's mother, Angie Douthit, has been diagnosed with stage four brain cancer, ET has learned.
A rep for McKee tells ET that Douthit has three large masses on the brain, as well as masses on her lungs and blood clots throughout her body. The rep says that unfortunately, it's not looking good -- she had surgery on Wednesday to see how far it has spread and it covers the entire brain.
"All prayer warriors. Please pray for my mom. What we thought was bronchitis turned out to be 3 masses on her brain, 1 large imone in her," McKee revealed via Twitter ahead of her mother's procedure. "Lungs and multiple blood clots. We are in shock and devastated. I'm sick. I'm so sick and want to wake up from this nightmare."
McKee also took to Instagram earlier this week, sharing a sweet collage dedicated to her mother.
"The most amazing woman I know," she captioned it. "She taught me everything I know. She is the only reason I am the woman I am today. I love you Mom. I'm devastated, I'm angry, I'm shook.m, I cant breath. You are everything. Please pray @angiedouthit."
A GoFundMe page has been created for Douthit, in hopes of raising $25,000 as she undergoes radiation and chemotherapy.
"Angie is a school teacher and doesn't have much, the family is asking for prayer during this difficult time," the description on the page reads. "We have come together for Mackenzie McKee and her family to help Angie get the best treatment that is available to help her fight the fight ahead of her.#HelpSaveAngie."
