Fans are worried after Britney Spears' mom Lynne posted a cryptic message to Instagram that reads, "When God’s warriors go down on their knees, the battle is not over; it has just begun." She captioned it "This is faith!"

Is she referring to Brit's recent hospitalization in a mental facility where she's seeking treatment following a difficult time with her father Jamie's health? Jamie Spears has been battling a serious colon issue and stress and worry over his condition is what seems to have triggered Britney's mental health issues.

Of course Brit was in a downward spiral in 2007 and was subsequently hospitalized in 2008 at which time a judge put her under a conservatorship led by the singer's attorney and her father. Andrew Wallet, the lawyer assigned to the care and keeping of Britney's estate and business matters for the past ten years, recently quit as co-conservator so Jamie is now the sole person in charge -- and at a time when he is battling very serious health issues.

Britney postponed her Las Vegas residency at the MGM Grand in January, following the family's announcement about her father's poor health.

Of course Lynne's post could also be referring to her ex-husband's battle ... but it's a woman in the photo, kneeling and praying -- so is the "battle" she mentions, referring to daughter Britney's mental health battle? We're praying for you, Brit!
