Katie Holmes dropped into a dance class in Manhattan yesterday afternoon. She was dressed in a casual denim shirt, her favorite Isabel Marant black booties, and a large red crossbody bag. Earlier in the day Katie and Suri welcomed Tom Cruise home from his lengthy trip around the globe. Tom visited Asia, Europe, and South America promoting his latest spy thriller, Mission: Impossible — Ghost Protocol. The film opens on IMAX in limited screenings today and Tom is getting rave reviews for his stunt work and impressive acting. It will likely be a busy weekend for the Cruise-Holmes household leading up to Monday's Big Apple premiere of the fourth Mission: Impossible film.
