Katie Holmes and Suri Cruise stuck together last night to shop around downtown Vancouver and pick up drinks from Jugo Juice. The girls are back in Canada saying hi to Tom Cruise as he shoots Mission Impossible 4: Ghost Protocol after venturing north of the border for the same reason a few weeks ago. Katie and Suri did go back to LA between Canadian visits so that the busy working mom could shoot Jack and Jill. Suri was able to join Katie on set as well, and even made a few new furry friends in the process. Katie's next stop may be at Sundance, where her movie Son of No One is set to debut with the confirmed attendance of her costar Channing Tatum.
