Police were called to Britney Spears’ house after she deleted her Instagram account

Britney Spears‘ fans thought something was seriously wrong with the singer after her Instagram account disappeared … and called the police to her home to see if she was in danger.

Law enforcement sources tell TMZ Britney deleted her Instagram account — something she’s done many times — sometime in the past 12 hours. For some reason, fans became alarmed, thinking the deleted account meant Britney was in trouble … and called Ventura Co. Sheriff’s Office.

Sheriff’s Office deputies then went to Britney’s home and determined there was no reason to believe she was in danger. It’s unclear if they spoke to Britney directly or if someone else assured them she was okay.

The incident comes less than two weeks after Britney was spotted at a local restaurant, witnesses tell us she became “manic”, frustrates her husband, Sam Asghari, to the point of getting up and walking. Video, obtained by TMZ, showed Spears babbling nonsense at the table.

As we reported, Britney recently changed her name on her Instagram account to River Redposting a video dancing and announcing, “I changed my name to River Red” … and below, “don’t underestimate the power of purity.”

TMZ broke the story Britney started recently showing her Calabasas home off-market to potential buyers. She first bought the house last year — but we’re told she was never really a fan of the place — buying it for $11.8 million and now selling it for $12 million.
