Pop superstar Rihanna has released her collaboration with Kanye West and Paul McCartney, called 'Four Five Seconds'.

Rihanna has released a collaboration with Kanye West and Paul McCartney, titled 'Four Five Seconds'.

The single marks the first time Rihanna has released new material since 'Jump', which came out almost exactly a year ago. Rihanna - who's collaborated with Kanye before, on the tracks 'All of the Lights' and 'Run This Town', which also featured Jay Z - has promoted the new tune on her Twitter account and posted a link to the iTunes store.

British singer Sam Smith has already taken to Twitter to voice his approval of the new single.

The 22-year-old star tweeted: ''I KNEW RIHANNA WOULD SMASH IT (sic)'' The record follows Kanye's own collaboration with McCartney, titled 'Only One', which prompted a spokesperson for the hip-hop superstar to say it would be the first ''publicly available recording from what has become a prolific musical collaboration between these two legendary artists''.

For McCartney, meanwhile, the single marks another surprising career move, following his contribution to the soundtrack of Destiny, which was one the biggest-selling video games of 2014.

The 72-year-old music legend has collaborated with a host of big names in the past, including Stevie Wonder and Michael Jackson.
