Katie Holmes was spotted in public for the first time since announcing her divorce from actor Tom Cruise on Monday, and she was quickly swarmed by paparazzi and anyone else in the area with a camera.

She mostly kept her head down during the walk out to her car, but was smiling the whole way.

The newly single star was seen outside of Manhattan's Parsons School of Design leaving a taping of Project Runway: All Stars. She'll be a guest judge during an upcoming episode of Heidi Klum's fashion show.

Sources involved with the show said that Katie arrived on schedule and was in good spirits, appearing happy to be there despite her impending court battle with Cruise over custody of their six-year-old daughter, Suri.

TMZ.com reported on Monday that, according to Katie, the couple's marriage was "irretrievably" broken late last year and that Tom was blindsided by the divorce filing.

Katie filed for divorce in New York State, where custody laws differ than in California and courts are more likely to grant her sole custody of Suri, which she has asked for in her divorce filing, in order to keep the child away from the Church of Scientology.
