Beyonce: LAPD Target Beyhivers For Alleged 'Becky' Hack

Beyonce's most rabidly loyal fans took things up a notch and hacked her one-time nemesis Rachel Roy ... at least that's where the clues are pointing the LAPD.

You'll remember, Rachel had a rumored history with Jay Z and took heat from the Beyhive when "Lemonade" dropped. Didn't help that a few hours after the release Rachel posted a pic with the caption, "Good hair don't care" -- stirring 'Hivers to think she was "Becky with the good hair."

According to docs, obtained by TMZ, Rachel called cops a few days later saying her Gmail and iCloud accounts had been hacked. She also said her cell phone number had been changed without her permission.

In the docs, Rachel makes it clear ... she believes all the trouble stemmed from that "Good hair don't care" IG post. Remember, she'd also been heavily spammed on all her social media with bee emojis -- the Beyhive's calling card.
