Rihanna reunion set for Supafest

Former couple Chris Brown and Rihanna could make their first public appearance together at the Brisbane leg of the urban music festival Supafest on Saturday.

Rihanna is in Australia for the Sydney red-carpet premiere of her film Battleship.

Meanwhile, Brown will be in the country for the national tour which finishes in Perth at Joondalup Arena on April 22.

And according to reports, the pair will perform together in Brisbane, marking the first public appearance for the one-time couple since Brown assaulted Rihanna almost three years ago.

The pair recently collaborated on Rihanna's track Birthday Cake and Browns song Turn Up The Music.

While Brown's reps have denied the rumours, a rep for Supafest told an Eastern States newspaper it was still "a possible scenario".
