Halsey threw her annual Halloween party last weekend called “Halsey Presents: Almost Famous is an experiential Halloween Party in Hollywood, celebrating the Rockstars of the 60’s, 70’s, 80’s & 90’s.”
She was dressed as Marilyn Manson, as she posted on her Instagram during the party.
She also performed an iconic song with an iconic artist at the party.
One of the special guests was Avril Lavigne, with whom she performed "Girlfriend".
