Billie Eilish has come under fire for using a racist slur and mocking Asian accents in resurfaced footage.

The controversial videos of the singer, 19, were posted to TikTok on Monday (June 14) by user @lcxvy and showed her saying "ch*nk" – an offensive slur used by racists to refer to those of Asian descent.

A second clip showed the star, who recently featured on the cover of Vogue magazine, allegedly mocking an Asian accent as her brother Finneas criticized her for speaking in a "black accent".

At the time of writing, the context and date of the clips were unknown.

The video left fans of the pop singer shocked – with some calling for her to be "canceled". However, others defended her behavior by stating that she has Tourettes.

Billie revealed that she suffers from the disorder in 2018, however, pointed out that she experiences physical tics instead of verbal ones.

Reacting to the videos, one TikTok user wrote: "No becuz I love her sm and I am attached to her but now I'm very disappointed [sic]."
