UFC middleweight champion Anderson Silva has "Bieber Fever."

The pound-for-pound kingpin was a special guest for music sensation and teenage heartthrob Justin Bieber at a concert in Rio de Janeiro, Brazil.

The video shows Silva stepping onto the stage, waving around a Brazilian flag and busting out a few dance moves.

Could we be looking at the next contestant on Dancing with the Stars?

Bieber, an MMA fan, took to Twitter to poke a little fun at "The Spider" after the show.

"Ok it's on!! The fight has been announced...me vs. @spideranderson – I am NOT the heavy favorite. Haha," Bieber posted along with the included picture.

Silva's notoriety only seems to be growing, as he just finished a video shoot with famous Brazilian recording artist Marisa Monte. Now, he's onstage in front of thousands of people, tearing it up with Justin Bieber.

"Really happy to meet you Justin..Welcome to Brazilian Tour," Silva posted. "Thanks to invited me, hope see u in LA soon let's training over there, nice meet you again Bro."

After seeing this video, there is one question in particular on the mind of every MMA fan:

What is Chael Sonnen going to say?
