After Sierra had gone public with the accusations, Runik had put out his response to it on his Instagram and YouTube.
In a video titled 'The Truth Behind Me and Sierra,' he explained what was going on behind the scenes that most people were unaware of.
Right off the bat, he confirmed his break up with Sierra and explained they had split the moment she made the allegations.
In the video, he showed clips of him and Sierra arguing, and in one of the videos, he called her racist, as Sierra allegedly asked him to go back to Mexico.
He also showed different clips of Sierra "attacking" him and "smacking and kicking" his phone out of his hands.
The YouTuber also took to his IG stories and posted evidence of him being scratched and stabbed by Sierra.
There is a lot of back-forth going on between the former couple, but fans have to wait and watch to see how this will unfold.
