Over the weekend stars were dressed for pre-holiday festivities, partying, shopping and traveling in the coolest of clothes.  California girl Gwen Stefani has certainly adapted to the British lifestyle.  The No Doubt singer looked smashing in lovely layers as she walked the streets of London.

Krysten Ritter celebrated her belated birthday in Las Vegas looking sharp in a blue and black romper.
