The best part of Halloween falling on a Monday is that you have the whole weekend before to dress up, possibly multiple times. Clearly celebs are just like us, because over the past few days they've been busting out their Hallow's Eve best, from Katy Perry's mic dropping Hillary Clinton to Beyoncé channeling Salt-N-Pepa and Enrique Iglesias just freaking us out.

Here are some of our favorites:

Beyoncé and fam pushed it real good as Pepa from Salt-N-Pepa (Jay Z also got in the throwback mood)
