Did Selena Gomez go commando while singing at Boston bash?

Selena Gomez sparked the underwear riddle after she appeared to perform without pants in Boston recently.

The 20-year-old starlet was singing live at the AMP Radio Birthday Bash when the front of her cut-out dress parted ways most immodestly exposing her underwear, the Sun reported.

The mishap happened as the singer bounded across the stage with her hand raised in the air.
