All girl group Girls Aloud were smokin’ hot in little black dresses and wide GA belts at a World Aids Day celebration held at London’s G-A-Y.  Ozzy’s better half, Sharon Osbourne hosted the event, while daughter Kelly was also on hand to present awards.

Jesse Metcalfe, member Nadine Coyle’s on again/off-again boyfriend, made a suprise appearance a the event, which have sparked rumors that the couple could be back on – again, while some have even speculated that the couple are engaged.

The concert, which also featured Sugababes and Westlife and which celebrated G-A-Y’s 15th anniversary, raised funds for The Elton John Aids Foundation.
