Actress Katie Holmes isn't letting her upcoming divorce battle with Tom Cruise get in the way of her work - the fashion icon turned up to shoot a guest spot on U.S. TV show Project Runway: All Stars on Monday.

Sources close to the show have revealed Holmes was on time for the shoot on the style contest, which tapes at Parsons New School of Design in New York City, and she appeared happy to be there.

Holmes filed for divorce in New York last week.
