On Thursday Fergie hosted Voli Light Vodka's Holiday Party benefiting Cell Phones for Soldiers at SkyBar at Mondrian in Los Angeles. The singer sizzled in a red sequined dress and silver stilettos.

Joanna Krupa from "The Real Housewives of Miami" also attended the event and showed off her legs in a black lace mini dress.

"The Big Bang Theory" star Kaley Cuoco opted for a dizzying multi-colored sequined pantsuit for the party.

Cell Phones for Soldiers provides free communication services to active duty military members and veterans. The program was launched in 2004 to keep military families connected.
