Sienna Miller and Tom Sturridge stepped out for a romantic walk in London this morning. Tom pulled up his shirt to give a peek at his abs, which have nothing in terms of hair compared to his very scruffy face. Tom and Sienna shared a kiss during another stroll earlier in the week. Sienna is gearing up for her latest Twenty8Twelve presentation along with sister Savannah after recently returning home from a trip to Ethiopia with the International Medical Corps. Tom and Sienna also recently entertained friends Robert Pattinson and Kristen Stewart in the UK. Kristen is currently there shooting Snow White and the Huntsman and Robert visited earlier this month, though is now back in the states.
