Pop stars One Direction have expanded their business empire by launching a cut-price jewellery collection.

The boyband singers, who are already working on their own perfume line for female fans, have now put together a range of charm bracelets, name necklaces and watches for U.K. chain Argos.

Prices start at $21.60 (£13.49) and pieces include a charm bracelet featuring pictures of the boys' faces and coloured plastic watches.

One Direction follow in the footsteps of fellow boyband JLS, who have also launched a jewellery collection with Argos.

The band's first fragrance is due for release later this year (13) and is set to go head-to-head with previously released female-focused fragrances by pop rival Justin Bieber.
