Jennifer Lopez Transforms From Sleek Sexy to Rocker Chic (PHOTOS)

Which Jennifer Lopez look do you prefer: sleek and sexy or ’80s rocker chic?

The American Idol judge made a dramatic wardrobe change on Tuesday when she made two different appearances in New York City. The singer first wore a white minidress with sexy skin-baring cut-outs (no Spanx for J-Lo!) when she filmed an appearance for BET’s 106 & Park. Later, the sexy singer let her hair down – and up – when she made an appearance at an album signing for her new album, Love?.
