JLS are currently in the studio working on their upcoming fourth album and have been teasing their Twitter followers with ideas for potential collaborators. 

The popular boyband took to the social networking site last night, January 22, and wrote: "JLS and bieber collab?? Sounds like could be fun don't u think?? Axx"

The message was met with an overwhelming response from the group's fans and a short while later they added, "JLS and chris brown collab?! Sounds even more fun right?? Ax #JLSchrisbreezycollab".

Last week, JLS confirmed that they will release a single called 'Proud' for the fantastic Sport Relief charity and explained to Radio 1:

The boys and I we went to Uganda in October and we spent a week with some fantastic people and all of the money raised from the sales of the single are going to help people around the world."
