Beyoncé is being sued by a back-up singer for R87 million after it was claimed the star had stolen her music to write the hit song 'XO'.

The 33-year-old star and her company Parkwood Entertainment and Columbia Records have been taken to court over her hit XO after the back-up singer “Ahmad Lane” filed a federal lawsuit claiming she had stolen the music for the XO track

Ahmad alleges that Beyonce's current backing singer Chrissy Collins gave her a copy of his song XOXO after he passed on the track to her when the pair were working together for another artist.

However, the Queen B has fervently denied the claims in court documents obtained by Radar Online. The response reads: ''The two works at issue are entirely different songs that share no lyrical or musical similarity, other than perhaps the letters X and O.

''The two songs are completely different from a thematic perspective. ‘‘[They have different] melodic content and there is no meaningful similarity in pitch series, rhythm or rhythmic patterns, melodic development or structure”, TimesLive reports

The Grammy Award Winner also states that Lane hasn't filed a ''copyright registration'' for his track and asks for the R87 million payments or chargers to be dropped.
