Apple's market-leading iPod MP3 player has attracted yet another celebrity endorsement – this time from World Wrestling Entertainment (WWE) star Goldberg.

In a clip screened within this weekend's Summer Slam pay-per-view, the wrestler is seen wearing an iPod while training before a critical match.

A professional wrestler, Goldberg is one of the WWE's biggest stars. The clip will have been seen by an estimated 7.1 million fans in the US, with an unspecified number of international viewers.

WWE is big business – the company's 2003 annual revenues are expected to reach between $325 million to $350 million for income of $26 million.

Other celebrity iPod users include: Robbie Williams, Posh and Becks, Craig David, David Gray, Fatboy Slim, David Byrne and Moby, along with Daniel Bedingfield and P Diddy.

Macworld is hosting a Forum topic – Celebrity iPod users where we hope to assemble a definitive list of iPod-users.
