Rosie Huntington-Whiteley had quite the week, going on a Transformers: Dark of the Moon style streak. Though the Victoria’s Secret model rocked several designer looks from Gucci, Salvatore Ferragamo and Dolce & Gabbana, our fave one of her looks was courtesy of Michael Kors, who dressed her in a slitty black chiffon jersey dress and a black leather asymmetric belt with nude and black ankle cuff stilettos for her Rio De Janeiro photocall.

Jennifer Aniston has hed her good girl image in more ways than one! The sexy star, who has recently been under blast for pulling an Angelina, hit the streets of NYC—exposing her panties!  Though we loved her Michael Kors sarong skirt, it was totally see-through and not quite her style.

And Lady Gaga wasn’t just the wackiest star of the week, but the tackiest as well! Wearing a green wig, the sassy singer hit a press conference for MTV Video Aid Japan charity event dressed in unflattering and feathered fashion.
