Rick Ross, Common and LL Cool J have been added to the Grammy's nominations ceremony performance line-up.

The rappers will be giving a special set alongside Grand Master Flash to perform the group's hit single 'The Message.' The collective will also be joined by Lupe Fiasco, Melle Mel and Scorpio.

Other performers who were previously announced, include Rihanna, Usher, Lady Gaga, Britney Spears and Ludacris.

The night - which will be hosted by LL Cool J and will announce the nominees in several categories - will air this Wednesday in the US, while the actual award ceremony takes place in February 2012.
