Jason Derulo has put his collaboration with JLS on hold.
He told The Daily Star :'Right now I'm trying to finish up my album so I wouldn't go and write a song for someone else. My focus is on myself.
'I can't believe JLS are on their third album already. Things are much faster here than in America. People crank out albums one after another, which is awesome.'
