Halsey recently performed with iconic singer Alanis Morissette.

Halsey said Morissette taught her to write “the best f**k you” songs.

She said without Morissette, she may not have ever written her biggest song to date, “Without Me.”

She released “Without Me” after breaking up with G-Easy.

G-Easy reportedly cheated on Halsey.

They dated for a year and released “Him & I” together.

Halsey performed “Alanis Interlude” with Morissette.

The “We Can Survive” concert had several performers like Garbage, One Republic, and Weezer.

Halsey previously talked about her struggles with her mental health.
