Sandra Bullock & Louis: California Christmas Party!

Sandra Bullock and her adorable son, Louis, get into the Christmas spirit as they go to a holiday party together on Saturday (December 11) in Santa Monica, Calif.

The 46-year-old actress put a cute Santa hat on Louis at the party!

Kids at the party had the chance to ride a horse – Louis tried it out, but it looks like he was a little apprehensive and wanted to stay with mom instead!

FYI: Sandra is wearing Hudson jeans. Sandra is using her BOB Revolution stroller!
