Willow Smith happens to celebrate her birthday on one of the best holidays on the calendar – Halloween – and mom Jada just couldn't resist posting the most adorable throwback of her baby girl decked out in a spooky costume.

"To my little princess of all things... you are 16!!!!! I love you my little spooky girl:) You make me so proud. Happy Birthday! Your mom," Jada tweeted.

The message was accompanied by a throwback photo of Willow dressed as a little vampire princess.  

No word what the singer, activist, and artist has planned for her 16th birthday or if she's getting dressed up for Halloween. Maybe she'll bring back the vampire princess costume or go as herself.

Back in 2010, when asked what she planned to be for Halloween, Willow said, "I'm gonna be myself, and I'm gonna go around the neighborhood saying, 'Do you like Willow Smith?' And then I'm gonna be like, 'Ta-da! It's me.' " 

Still, Willow may have other things on her mind after recently joining protests in North Dakota against the Dakota Access Pipeline, so maybe she hasn't even had time to come up with a costume idea.

Either way, whether protesting or celebrating with Halloween festivities, we hope Willow has a happy birthday.
