Sarah Jessica Parker had the help of a nanny yesterday to stroll NYC with her daughters, Tabitha and Loretta. The ladies walked around the city where they spend part of the Summer when not at their vacation places in Ireland or the Hamptons. They're in the Big Apple currently as Matthew Broderick recovers from back surgery. We had a peek at SJP's happy home life in the August edition of Vogue, which looked at how the actress manages to balance raising three kids with a powerful film career. One job off SJP's plate, though, is with Halston; Sarah Jessica Parker and Halston parted ways recently after a year and a half of collaboration. She'll have more multitasking to do this month in the run-up to the release of I Don't Know How She Does It in September. The movie opens on Sept. 16, and it also stars Christina Hendricks, Seth Meyers, and Pierce Brosnan. Next up for SJP will be a stint in a recording studio, as she's officially joined the cast of the animated film Escape From Planet Earth.
