Katie Holmes chatted on her cell phone Saturday while out in NYC. Yesterday, she stepped out with her daughter Suri Cruise. The girls headed to Chelsea Piers, where Suri took a ballet class. Suri's got a packed schedule between her Monday-through-Friday routine at school, with additional classes on the weekend. Katie's also becoming more and more booked as the opening of her Broadway play Dead Accounts nears. Katie, who made a Broadway debut in All My Sons back in 2008, will be back on the Great White Way opposite Judy Greer and Josh Hamilton when previews begin on Nov. 3. The show runs for 16 weeks only.
