Leona Lewis and her recording company Syco unveiled her new single 'Collide' on the 15 July when it was played on BBC Radio 1, and shortly afterwards she was accused of plagiarising the song.
Now, if Leona Lewis wants to officially release her single, she will have to fight an injunction in the High Court, brought by Swedish DJ Avicii.
Avicii, real name Tim Bergling, claims that he first wrote the instrumental part of the song in October last year.
He was then signed to the Ministry of Sound label and intended to release his song, called 'Fade into Darkness' after finding a vocal track to complete it.
A track was discovered, called 'Collide', and Ministry planned to release Bergling's track in October this year.
However, Syco (Simon Cowell's recording company) heard 'Fade into Darkness' and decided they wanted it for Leona Lewis. They contacted Arash Pournouri, Bergling's manager, who rejected their offer.
'Collide', sung by Lewis, was later player on Scott Mills' show on Radio 1 and a video was released on YouTube.
Pournouri claims that 'Collide' "is a straight re-recording" of the earlier version of the song which contained the instrumental written by Bergling.
Leona Lewis has denied the claims, saying: "With regards to my song, Avicii was aware and agreeing publishing splits for himself and his manager. When Avicii sent his track out to have a song written over it, I totally fell in love with this version and I think he's super talented."
The High Court will hear the plea for an injunction on Monday (8 August). If the injunction is granted, 'Collide' will not be permitted to be released on 4 September.
