Kanye West has been added to the list of performers at the BRIT Awards after Rihanna reportedly pulled out.

The pop star was said to have signed up to debut a new track at the prizegiving in London on Wednesday night (25Feb15), but a U.K. report suggests she pulled out of rehearsals on Monday (23Feb15) and axed her set.

West has since been added to the line-up to replace his FourFiveSeconds collaborator.

A source tells Britain's The Sun newspaper, "Everything was prepared for Rihanna's performance but she was a no-show... (But) Kanye is just as big a star as Rihanna and is always good value at awards shows."
