Parties! The style, stars and scoop from Hollywood's hottest events

Kate Beckinsale caught a case of last-day-of-spring fever when she attended the UK premiere of Live Free or Die Hard in London. Beckinsale and husband Len Wiseman were flirty and fun all the way from the red carpet at the Empire Leicester Square theater to the after-party at hip club Cirque. The comely couple took over the dance floor and engaged in some PDA in full view of photographers while Die Hard star Bruce Willis worked the room in true leading man fashion.
