"Becky with the good hair" should've tried to be "Becky with the good anti-malware" -- that is, if Rachel Roy really is who Beyonce was referring to.

Roy, the fashion designer accused of being Jay Z's mistress, reportedly had her private emails hacked recently.

An unnamed source told London tabloid The Sun that Roy told her friends her personal files were stolen and that they could expose damaging revelations.

Roy became the target of Beyonce fans when the designer posted and then deleted a photo on Instagram with the caption "good hair, don't care."

The BeyHive quickly swarmed her social media pages after making the connection to Roy and the lyrics from Beyonce's "Sorry."

Roy publicly denounced her involvement in any affair and told People magazine, "There is no validity to the idea that the song references me personally. There is no truth to the rumors."
