Rihanna, Kanye And McCartney Video Released

The video for Rihanna's new track FourFiveSeconds has been released online which sees her teaming up with Sir Paul McCartney and Kanye West.

Rihanna tweeted a link to the black and white footage which shows all three stars wearing denim, with the former Beatle on guitar.

The video comes ahead of the trio's appearance at the Grammy music awards in Los Angeles this Sunday.

Meanwhile there is speculation that Rihanna could be joining Kanye on tour later this year.

A photo/flyer was reportedly sent to an entertainment website by an "anonymous, reliable source close to the camps".

The pair headlined a pre-Super Bowl concert on Saturday.

Rihanna sang during Kanye's Glow in the Dark tour in North America in 2008.
