Britney Spears has deactivated her Instagram account numerous times in recent months, and she did it again Wednesday, a few days after changing her username to River Red. In response to the accounts disappearance, some of her fans called her local police department asking them to check up on her. The cops did indeed show up at her house, but they quickly determined that nothing was wrong. Now Spears (pictured above with husband Sam Asghari) has posted a message on Twitter that essentially amounts to “leave Britney alone.”
