Just as Sarah Geronimo was about to begin with her performance of Rihanna's "Where Have You Been," the lapel microphone attached on her back from her last song fell off and got caught in her dress.

Sarah asked for help from her back up dancers to take the lapel mic set off her, but the song has already started.

So, with the lapel mic hanging from her back, Sarah breaks into the opening lyrics of "Where Have You Been" and gave an exciting performance for her audience.

Watch the second night of Sarah's 24/SG concert at the Smart-Araneta Coliseum on July 21.
