Rihanna doesn't seem the type to be easily shocked. In fact, she's often the one doing the shocking. This past Saturday during her Anti tour, however, one fan blew her away when Rihanna turned the mic to the audience during "Four Five Seconds." Her face is priceless.

In another video, you can hear Rihanna going, "Oh shit."

At the end of the song, she shook her fan's hand and thanked him. There is an appropriate freak-out—his friend even drops to the ground.

The fan, TJ, says on his Instagram bio that his "dream came true" that night.
