Who better to talk about an eclipse than some big stars?

Katy Perry, Paris Hilton and Chelsea Handler are only some of the big names who are chatting about the solar eclipse ready to take over the sky today (August 21). They and more of Hollywood's greatest — like we — eagerly swarmed Twitter to share their thoughts on the highly-anticipated celestial event, the views of which will stretch across the continental United States.

We're particularly fond of Sarah Michelle Gellar's tweet, in which she references a Buffy the Vampire Slayer episode in where the town mayor becomes a demon during an eclipse. Way to go retro in honor of the big day.

Check out some of the other great tweets below. And don't worry, you don't need any special glasses to enjoy them.
