WATCH: Mystica goes beastmode against Duterte [video]

Ruby Rose Villanueva, more known as Mystica, has gone beastmode and lashed out at presidential candidate Davao City Mayor Rodrigo Duterte in a video that went viral on Facebook.

The singer, dubbed Celebrity Rock Diva and Split Queen, claimed that she was approached by prominent politicians and offered money to change her stand against the presidential front-runner.

In the video, Mystica expressed doubt that Duterte can eradicate crime in the whole country in 3 to 6 months if elected president. She slammed the candidate's plan to enforce a curfew which, according to her, is comparable to what happened during Martial Law.

The recording artist also shared the story of her father who was allegedly murdered in front of his family during that era.

Warning: The following video contains foul language.

Mystica was criticized by Duterte supporters, majority of whom said she doesn't have credibility. Some even mentioned in their comments her sex scandal video and alleged use of illegal drugs.

The singer posted her video after news broke that Duterte topped the latest Social Weather Stations (SWS) and Pulse Asia pre-election surveys.
