Michael Jackson disappointed celebrity fans over the weekend when he took to the stage with a microphone - but refused to sing.

The reclusive singer made a rare public appearance at Ed Hardy owner Christian Audigier's 50th birthday party, which was also attended by Britney Spears, Stacy 'Fergie' Ferguson, Pamela Anderson and Snoop Dogg.

The 49-year-old singer joined birthday boy Christian on stage at the Petersen Automotive Museum in Hollywood to say a few words about the designer.

However, their excitement was short-lived when Michael simply said "Hello... Christian is the king of fashion", before retreating off the stage.

In contrast to the famous females' slinky dresses, Jackson looked out of place in his unusual combination of wet look trousers with a military/royal-themed blue satin shirt.

One reveller told The Mirror: "Everyone went mad when he grabbed the microphone. The mood was electric.

"But sadly there was no impromptu gig. It was a shame because he looked in pretty good shape. He was obviously just putting in an appearance for his old pal Christian."

Jackson made the whistle-stop visit to Los Angeles from his base in Las Vegas.

The Thriller singer has been residing in Nevada's Sin City since last year with his three children Prince Michael, 11; Paris Michael, 10; and Blanket, six.

Back on the scene: Britney was escorted to the party by father Jamie Spears

Meanwhile, a chic-looking Britney was escorted by her father Jamie Spears and agent Jason Trawick.

The singer appears to have turned over a new leaf following her recent fashion mishaps and cut a sleek figure in a black bandeau dress and Christian Louboutin high heels.

While Michael failed to sing, former The Black Eyed Peas singer Stacy 'Fergie' Ferguson happily performed to the celebrity crowd.

Newly-single Pamela Anderson was also in attendance in a miniscule grey lurex dress, but unwittingly flashed her knickers at some of the crowd when she stuck her arm in the air on stage with Christian.
