She's still no Spinderella, but Sarah Michelle Gellar isn't half bad at rapping. 

The "Buffy the Vampire Slayer" star donned a blue gown to star in this video as Cinderella facing off against none other than Belle from "Beauty and the Beast." 

Gellar starts her rap by dissing Belle, rapping, "Another princess in my shadow come to covet my crown / You clowns wanna throw down with the best in a gown?" 

Whitney Avalon, creator of the "Princess Rap Battles" series, told People that she reached out to Gellar after the actress tweeted a "Princess Rap Battle" video. 

"W e thought, 'How incredible would it be to put her in this gorgeous gown and have her be Cinderella?' Fortunately, she felt the same way," said Avalon. 

We get the feeling Gellar's young daughter, Charlotte Prinze, wasn't opposed to her mom dressing up and throwing down as one of the greatest Disney princess of all time, either.
