Katie Holmes escorted her daughter, Suri, to a Halloween party in LA yesterday. The actress, who was on a break from shooting Jack and Jill, didn't wear a costume herself, but Suri was in her latest dance-inspired get-up. It was an afternoon for just the girls, since Tom Cruise is shooting Mission: Impossible 4 in Dubai. Tom's lining up more future projects, but he's still thinking about his recent stay in Prague. Last week's installment of his fan club's newsletter was an open thank-you note to the city, as Tom looked back on his family's stay abroad. He wrote, "In addition to filming in numerous breathtaking locations, my wife and I enjoyed early morning walks through the cobblestone streets with time to admire the sheer elegance of the architecture and the work of local artists displayed in many of your city’s fine shops."
