Teen sensation Justin Bieber will have his merchandise marketed by Prince Williams in laws, the Middletons, through their highly successful website according to The UK's Sun newspaper.

The king of teen pop will be rubbing shoulders with almost royalty as it is alleged that the Middletons have signed a deal to sell Justin Bieber merchandise through their online shop Part Pieces.

The website says: “We've got Bieber Fever! Teenage girls around the world go crazy for the Bieber. The pop star now has his very own partyware.”

The site is reported to be selling a array of Bieber items including straws, rosettes and the chance for fans to be able to pick up the Ultimate Party Kit which includes a set of specially mad plates, cups, napkins and balloons all based around the image of Justin Bieber.

The Party Pieces website helped to make Carole and Michael Middleton, the parents of Kate Middleton who married Prince William in April, millionaires as they provide party ware from the factory they run close to their home in Berkshire.

Justin Bieber recently told fans that he had watched the royal wedding on television and had sent his congratulations to the couple while he added that he thought Pippa Middleton was a “hit”.
