It was announced earlier this week that Rihanna will be performing at tomorrow's Grammy Awards with Bruno Mars and Sting, but it looks like there may be some additional star power joining them on stage.

Nothing has been confirmed, but Rihanna posted a picture to her Instagram account labeled #BackstageLife of her with Damian and Ziggy Marley, suggesting that they may be involved in her performance. An additional photo also surfaced of RiRi, Bruno Mars, Sting, and the Marley brothers together backstage (click through to see above).

Could this mean that the sons of the legendary Jamaican reggae singer Bob Marley will be performing with Barbados' own superstar Rihanna tomorrow night? That would be quite a moment for the Caribbean if so, though there is still the possibility that Damian and Ziggy were just visiting rehearsals and showing love.

Tune in to the Grammy Awards tomorrow night at 8pm EST on CBS to see what goes down.
