Robert Pattinson's hometown fans turned out in force this afternoon in London! He received a warm welcome at the UK premiere of Water For Elephants along with his costars Reese Witherspoon and Christoph Waltz. Their latest international stop came on the heels of screenings in Paris, Barcelona, and Berlin. Reese was on Rob's arm during today's event, while across the pond his real-life love, Kristen Stewart, hung out in NYC. She had a big night yesterday at the Met ball, where she rocked a Proenza Schouler dress to mingle with the label's designers Jack McCollough and Lazaro Hernandez. Kristen and Rob have been apart tending to work commitments since their hot Easter getaway to St. Thomas. The pair stripped down to shoot Twilight's honeymoon night scene, with Rob going shirtless and Kristen breaking out a bright green bikini. Rob and Kristen also graced the cover of Entertainment Weekly as Edward and Bella, and this week exciting new Breaking Dawn stills were released showing more of what's to come in the final installments of the much-loved saga. Robert is getting lots of love for his role of Edward, as he's up for a MTV Movie Award in the category of Best Male Performance!
