Rachel Roy believes a Beyonce fan hacked her phone and email after she was accused of being Jay Z’s former mistress and the ‘Becky’ referred to in the singer’s Lemonade album.

The mother-of-two, 42, was horrified when her Gmail and iCloud accounts were hacked and her mobile phone number was changed without her permission in the days following the album’s release on April 23.

The Los Angeles Police Department (LAPD) are said to have obtained a search warrant for phone and email records and believe the perpetrator is a Beyonce fan, according to TMZ.com.

Fashion designer Roy had been forced to deny accusations that she was ‘Becky with the good hair,’ but she believes it was the speculation among fans that directly led to her being hacked.

In documents seen by TMZ, Roy makes it clear she believes the hacking stemmed from her posting an Instagram photo just hours after Lemonade’s debut.

She captioned it: ‘Good hair don’t care, but we will take good lighting, for selfies, or self truths, always. Live in the light #nodramaqueens’

As fans will remember, Beyonce sings about a love rival, who she describes as ‘Becky with the good hair’ in the song ‘Sorry.’
