Who were the style winners and sinners this week?

From the red carpet of the most exclusive events to the city streets, Hollywood’s hottest stars were dressed to rock and shock in the best, worst and wackiest fashions – and Breaking Celebrity News has all the photos in our weekly feature.

Emma Stone was busy promoting her new move, The Amazing Spider-Man, all over the world, making style statements every step of the way. Our favorite look of the adorable actress was at the Paris premiere of her highly anticipated flick, where she dropped jaws in a glam-to-the-max Gucci gown!

Oh, Miley Cyrus! The newly slimmed-down star flaunted the results of her gluten-free diet and Pilates workout routine all over Los Angeles, flopping on the fashion front in a variety of indecent, butt-cheekbaring cutoff jean shorts and crop top ensembles.

As for wacky, Katy Perry grabbed plenty of attention at the 2012 MuchMusic Awards in Toronto.  After wearing a totally goth gown on the red carpet, she hit the stage for her performance, giving the title of her song and upcoming movie “All of Me” more meaning, leaving little to the imagination in a sheer, nude bodysuit.
