Melissa Joan Hart has had an "intense" week – because her mother, Paula Hart, underwent an eight-hour surgery on a brain tumor, the actress reveals on her MySpace Celebrity page
"All of my 6 siblings and I gathered at my house and the hospital for the entire week to be strong for each other," Hart, 33, writes. "She is out of the woods and on her way to recovery, luckily she is a good healer and has 7 children to lend a hand in times like these."
As for how she's getting through this tough time, the former star of Sabrina the Teenage Witch
, who recently posed on the cover of PEOPLE
, has turned to her faith.
"Prayer is a big part of my life and it was very crucial last week for my mommy," Hart blogs. "I ask that you keep her in your thoughts and prayers as she fights her way to a full and wonderful recovery. I love you Mommy!!!"
Paula Hart, 53, was the executive producer on Sabrina
and other TV productions that have involved her children. Her latest production was My Fake Fiancé
, which stars Melissa and which premiered April 19 on ABC Family.
