They're getting acclimated quite quickly!

It's been more than a few months since Katie Holmes and Suri Cruise made the big move from New York City to Calabasas, California and now they're already part of their new neighborhood as the two attended a birthday party in the area on Saturday.

The 35-year-old actress was casually dressed in demin while her adorable daughter was in all white, mirroring her friend who accompanied them.

Glad to see the coastal switch hasn't affected their social lives!
