Robert Pattinson and Reese Witherspoon arrived at the Home House Private Members Club in London this evening. They were headed into the afterparty following the UK premiere of Water For Elephants earlier in the evening. Rob and Reese have been on the go promoting their film overseas since last week and they've made stops in Spain and France, though Rob was without his leading lady when he took care of press in Germany. The duo had more than just the success of their movie to celebrate tonight since Rob was also nominated for multiple MTV Movie Awards. Kristen Stewart was on the list of nominees as well, though she wasn't able to join Rob in England since she was among the many celebrities at the Met Gala in NYC yesterday.
