From the red carpet of the hottest movie premieres and events to the city streets, Hollywood’s hottest stars were dressed in winning and sinning style on Thursday – and Breaking Celebrity News has all the photos in our daily Best & Worst Dressed fashion feature.

Kate Beckinsale knows how to dominate a red carpet! The gorgeous actress stunned at the Los Angeles premiere of Underworld Awakening, wearing a gorgeous, crystal beaded Jenny Packham gown.

JoJo had a steak dinner style slip up in Los Angeles. The sassy singer was dressed for the summer months, wearing a colorful and very pink belly-baring ensemble, which hardly seemed appropriate for a fancy dinner at BOA.

Other style scores included Carey Mulligan in a tulip print Roland Mouret dress at the London Film Critics Circle Awards and Elizabeth Banks in a sexy Versace mini at The Cinema Society and Grey Goos
