Tom Sturridge, Sienna Miller Leave Lunch in London Pictures

Sienna Miller and Tom Sturridge stopped for lunch together yesterday at London's Mestizo Mexican restaurant then continued on with a loving stroll about town. Tom's beard is reportedly for On the Road reshoots, and his girlfriend, Sienna, doesn't seem to mind a lot of scruff. Tom costars alongside Kristen Stewart, Amy Adams, and Garrett Hedlund in the big-screen adaption of Jack Kerouac's famous novel, though the first On the Road stills show a very clean-cut Kristen and Garrett instead of Tom's hairy look. Sienna recently wrapped up her stint in the West End performing Flare Path on stage, and she and Tom celebrated their time off with a vacation in Ibiza.
