Nikki and Brie Bella called for fans to pray for their mother, Kathy Laurinaitis, before her brain surgery on June 30.

The “Total Bellas” stars revealed Laurinaitis, 55, has a mass on her brain stem that has been causing paralysis on her face.

“Our Mama Bella, our Gigi, our Gato is about to head into brain surgery. I ask for so many prayers, so much light and love sent her way,” Nikki, 36, wrote on Instagram along with photos of her mom with their family members.

Nikki, who is currently engaged to Artem Chigvintsev, is pregnant with her first child who is due this year. Her sister Brie, 36, is due to have her second child with her husband, Daniel Bryan, within two weeks of her twin sister.

“She’s loved by so many of us and just pray that her road to recovery is exactly what we are hoping for so we can put two new grand babies [sic] in her arms soon,” the former “Dancing with the Stars” contestant concluded her post. “Love you SOOO much Mom! You have a big Bella Army out here praying for you!!”
