Katie Holmes cracked a smile as she headed into Chelsea Piers in NYC yesterday. She picked up Suri from gymnastics class after the 6-year-old was dropped off earlier by dad Tom Cruise. Tom and Suri spent the last few days together and made the most of their father-daughter time by taking a quick trip to the Hamptons. While Tom and Suri were away, Katie fit in a spinning workout at SoulCycle. In the wake of her split from Tom, Katie's ramping up her work schedule. She has plans to return to Broadway this Fall in Dead Accounts, and will also show her Holmes & Yang collection at New York Fashion Week in September.
