Rihanna and Justin Bieber are due to perform at this year's Victoria's Secret Fashion Show.

They will be joined on the bill by Bruno Mars at the glitzy event in New York City on December 4.

The announcement was made yesterday (October 2) on the lingerie company's Facebook page. The show is set to be broadcast in the US on CBS.

Last year's event saw Maroon 5, Nicki Minaj, Kayne West and Jay-Z perform.

Rihanna meanwhile is currently in a UK chart battle with British pop stars One Direction, who both released new singles on Sunday (September 30).

The Bajan beauty released 'Diamonds' whilst One Direction unleashed 'Live While We're Young', with the two tracks set to go head-to-head when the chart is officially announced on Sunday (October 7).
