Elton Johns annual Oscars party, benefiting his AIDS Foundation, dished out a hefty dose of glam, thanks to four pop star guests: Katy Perry, Adam Lambert, Miley Cyrus, and Gwen Stefani.

A blue-haired Katy sparkled literally in her shimmery gown; Adam was a complete and total handsome hunk in his black tux; Miley was simply ravishing as she showed off her new haircut and figure in her dazzling, back-baring gown; and the always fabulous Gwen rocked it in her goth-glam black dress with red sequin flower accents.
