Lady Gaga Makes Pizza Deliveries for California Wildfire Evacuees

Lady Gaga is walking the walk when it comes to helping California's wildfire victims ... and she's doing it with arms full of pizza.

Gaga hit up a Red Cross Shelter in the L.A. area Tuesday night to deliver goodies -- food, coffee and other items -- to hundreds of people displaced by the Woolsey fire. No tip necessary. She's all good.

Can't say she's not a woman of her word. Remember, Gaga -- who was also forced to evacuate -- went to a shelter over the weekend and told evacuees she'd stand by them through the crisis.

Kinda perfect timing that Tuesday happened to be World Kindness Day, and Gaga encouraged others to follow in her footsteps.
