Watch Sarah Michelle Gellar as Cinderella in Latest Princess Rap Battle

Sarah Michelle Gellar in the 2015 video for "Cinderella vs Belle: Princess Rap Battle."

Once you've made a name as a slayer of vampires, rapping should be a breeze.

Sarah Michelle Gellar plays Cinderella in a very special installment of the popular YouTube series Princess Rap Battles. This time around, Cinderella takes on Belle (played by creator Whitney Avalon).

"Sarah had posted the first Rap Battle on Twitter, so we knew that she had seen it and that she was a fan," Avalon told People. "So we thought, 'How incredible would it be to put her in this gorgeous gown and have her be Cinderella?' Fortunately, she felt the same way." 

Check out their song -- complete with plenty of disses about both the Beast and glass slippers -- below.
