A teacher by the name of Kristen who attended Juicy J's 4/20 concert on Sunday was lucky enough to be brought on stage to dance alongside the rapper as he performed the hit song "23," featuring Miley Cyrus and Wiz Khalifa.  Once the woman was brought up he introduced her to the crowd and asked to see her twerk.  She hesitated at first, and then whispered in his ear that she is a teacher and didn't want the video to end up on WorldStar.

Juicy informed the crowd of her situation, but when the music began playing, Kristen turned around and busted it open briefly for the crowd's pleasure.  Afterward she danced around the stage before being escorted off.
