Maria Menounos told fans on Tuesday morning that her mom, Litsa, is suffering from a brain tumor.
The E! News co-anchor posted a photo of her parents exiting a private plane just hours before her mother was set to begin treatment.
"And so our journey begins. Mom is battling a brain tumor. She's a champion. Please pray for her full recovery," the 38-year-old wrote.
"Just landed safe and sound in la for treatments. Thank you to everyone sending love and support at this time. Oh did I mention it's her birthday week?:) #itsallaboutlitsa #standup2cancer #choosehappiness #wewillfight."
News of her mother's illness comes just five months after Maria got engaged to longtime boyfriend Keven Undergaro. Here's hoping Litsa will feel better in time to dance at her daughter's wedding!
