Robbie Williams' 99 Red Balloons

British pop prince Robbie Williams is planning a spectacular chart duet with 80s German pop star Nena.

The MILLENNIUM hitmaker approached the singer at this year's (03) ECHO music awards in Berlin - with the idea of performing her most famous hit together.

Nena says, "He wants to sing 99 RED BALLOONS with me. I'm looking forward to it like crazy. Robbie grew up with the song."

The two are planning to premiere their duet in July at the SCHALKE ARENA FOOTBALL STADIUM in Gelsenkirchen, when Robbie performs there on 13 July (03).
