Here's Anderson Silva like you've never seen him before -- dressing in drag and twerking like his life depends on it to pay tribute to a huge Brazilian pop star ... and we gotta say, dude's got moves!
The UFC legend shared his crazy dance routine on social media -- explaining that it's a tribute to fellow Brazilian Pabllo Vittar, a singer/drag queen who famously collab'd with Major Lazer last year.
"In the spirit of Carnival I pay tribute to my illustrious peer Pabllo Vittar," Silva said.
