Leona Lewis is finally back with Happy!

Simon Cowell is very angry with the recent leak incident of Leona Lewis latest single with collaboration with Nsync stud Justin Timberlake.

Police were already called to do some investigation on all the computers in Syco to check on possible hacking incident which leads to the distribution of “Don’t Let Me Down” track of Leona Lewis.

“Syco are working alongside the International Federation of the Phonographic Industry, the British Phonographic Industry, the police and investigators in this and they are making fast progress,” a company exec said in a statement Tuesday. “We will certainly look to bring charges against those who are responsible. We cannot give any more details at this stage for operational seasons.”

New album of Leona will be out on November.
