Britney Spears has sparked concern by deactivating her account for the fourth time in the past five months.
It comes amid fears from fans that the 41-year-old Toxic hitmaker isn't in control of her own account after sharing a number of unusual posts.
Among them included one gushing about her sister Jamie Lynn Spears, despite being estranged from her younger sibling for years and being vocal over Jamie's lack of support while she was under a conservatorship.
