Adding even further impact to weekend party performances by Black Eyed Peas beauty Fergie and I Try star Macy Gray was a surprise appearance by Michael Jackson.
The famously reclusive Billie Jean singer took to the stage at the 50th birthday celebrations of Christian Audigier - the French designer behind fashion label Ed Hardy. And the excitment among the pop legend's fellow guests, who included former Baywatch actress Pamela Anderson, Snoop Dogg, and 'American Beauty' Mena Suvari, was apparently palpable.
"Everyone went mad when he grabbed the microphone," reveals a fellow guest. "The mood was electric!"
Also helping Christian celebrate his milestone birthday at LA's Petersen Automotive Museum party was Britney Spears. The 26-year-old singer, who was accompanied by her father and a couple of gal pals, stayed for an hour and a half, but had left before fellow chart topper Michael put in his unannounced appearance.
