Rebeca Andrade was already to go for her floor exercise in the women's gymastics team final. Only problem was, her music wasn't.
The music started to play briefly as Andrade stepped on to the floor, but cut out suddenly. That's not supposed to happen in the home of samba.
A quizzical look washed over Andrade's face. After a brief delay, the synthesized version of Beyonce's "Crazy In Love" started to play.
She didn't appear too rattled as she went through her routine, but did stumble to her knees while trying to stick the landing on her final jump.
Judges gave her a 12.966, drawing boos from the partisan Brazilian crowd.
