Katie Holmes and Suri Cruise left NYC's Chelsea Piers yesterday with a new companion — the girls hopped into their car with a new dog! Whether or not the pet is theirs to keep, Katie and Suri are settling into life in the Big Apple before school begins. They made the most of their Summer together, jetting to visit the Holmes family in Ohio and frequenting the jogging path by the West Side Highway so that Suri was able to learn to ride a bike. Suri also logged plenty of time with her dad, Tom Cruise, including a fun trip to Disney World in Florida.

We're taking a look at some of their most exciting activities celebrities got up to this Summer. Jennifer Aniston and Justin Theroux skipped the beach in favor of the streets of Paris.
