Kirsten Dunst and Garrett Hedlund continued their break from filming and caught up with another famous face in London on Thanksgiving. The pair grabbed a drink with their On the Road costar Viggo Mortensen and were spotted chatting with him outside Christopher's American Bar & Grill. The couple have been all over London in recent days. Kirsten and Garrett took a romantic stroll around town last week, and yesterday they were all smiles during a casual dinner. Their busy schedules will likely resume soon with Kirsten returning to the set of her latest film, The Two Faces of January, which also happens to star Viggo, while Garrett is reportedly among the hot leading men being considered to star in Fifty Shades of Grey — who would you cast as Christian Grey?
