The glam factor was high on Thursday, as stars hit the red carpet and the streets dressed to rock and shock in designer duds -- and Breaking Celebrity News has all the photos in our daily fashion feature.

Katy Perry paid a visit to BBC Radio in London, dressed to impress in a sassy silver Matthew Williamson dress.  The sleek and chic mini featured a gorgeously embellished neckline, and hugged her curves to perfection.  She finished off the look with bright yellow Charlotte Olympia heels and a silver cuff bracelet, scoring herself the best look of the day.
