Beyonce sued for $7 million for plagiarismLos Angeles, June 14 (AZINS) Singer Beyonce Knowles has been sued $7 million by a backing singer who claimed the star had plagiarised her music to write hit song “XO”.

The 33-year-old and her company Parkwood Entertainment and Columbia Records have been taken to court over her hit single “XO” after Ahmad Lane filed a federal lawsuit claiming she had stolen the music for the track, reports femalefirst.co.uk.

Lane claims that Knowles'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 Grammy Award winner has denied the claims in court documents.

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 distinct from a thematic perspective."

The “Crazy in love” hitmaker also states that Lane hasn't filed a "copyright registration" for his track and asks for the $7 million payment to be dropped.
