JLS are offering fans the chance to have a chat with them as part of a new partnership with BlackBerry.

The British boyband are teaming up with the mobile phone company to help launch their new BBM Voice service.

The application allows users to make free calls to their BBM contacts on their phone.

BlackBerry are launching a competition that will see four fans get the chance to speak to their idols over the phone.

Interested parties are asked to follow @UK_BlackBerry on Twitter and from Monday (January 7) look out for tasks.

Speaking about their new partnership, JLS said in a statement:

"We all love BlackBerry and BBM, so we're pretty excited about the arrival of BBM Voice."

They continued: "With our hectic schedule, BBM Voice is a great way for us to keep in touch with friends and family back home. It's also a great opportunity to give something back to our fans and we're looking forward to giving four winners the chance to ask us their burning questions!"
