Lady GaGa has been tipped as the most influential sound of 2009. With her drag queen looks and outlandish style, this Italian/American singer from NYC (who went to school with Paris and Nicky Hilton) is about to bring back pop with style. At only 22, she has already written tracks for Fergie, Britney, New Kids on the Block and most recently, Akon, with her number one Just Dance. We just love her loud persona! Sequin hot pants, futuristic sunglasses and Thierry Mulger style silhouette in toe, her performances are quite a show, all produced by GaGa's in house team, who she likes to call Haus of Gaga. Despite no one knowing her real identity, there's no disguising this Christina Aguilera screwed up on Boombox pneumonia.
