The Toxic singer's Twitter and MySpace accounts were hacked and the messages posted on her page claimed she worshipped the devil.
However, several of the messages were deleted after Spears' management regained control of the account, reports China Daily.
The 27-year-old singer's Twitter feed has more than 3.7 million followers and is updated by herself and her "team" of handlers.
A message apologized for "any offense the hacker's messages caused." (ANI)
