Los Angeles, California - Olivia Rodrigo got some love from Ariana Grande thanks to her Wicked-inspired Halloween costume!

The 21-year-old pop star unveiled her costume for this year's spooky season with a new video shared on her Instagram page.

In the clip, Olivia and her longtime pal Iris Apatow showed off their looks as Wicked's iconic witches Elphaba and Glinda, respectively.
