Demi Lovato threw a crazy Halloween party Saturday night, and tons of celebs came out to celebrate.
The bash went down at Hyde nightclub in Hollywood. Among those who attended … Paris Hilton, Larsa Pippen, Jason Derulo, Jake Paul, Madison Beer, Hana Cross, EJ Johnson, Jayde Nicole, and Dorothy Wang.
Demi came as Pennywise from "It." Paris came as a schoolgirl. Larsa came in camo … check out the gallery.
Kylie Jenner was supposed to attend, but her driver got in a little fender bender and she ended up being a no show. She wasn't hurt and ended up hanging with Sofia Richie. BTW … Kylie was dressed as Madonna, circa 2003 VMA Awards.
We're told it was the first Halloween party Demi's ever thrown … so you can chalk her first one up as a pretty big success.
