When Courtney Love wants to rock out, she rocks out.

The former Hole lead singer spontaneously got up on stage to sing after a recent performance by the band MS MR.

According to a spy, Love, 48, "felt inspired" after the band rocked the Surf Lodge in Montauk on Saturday, and "jumped on the stage" to sing a few new songs. Unsurprisingly, the crowd at the Caliche Rum-sponsored show was "very excited" to hear Love wail, the spy said.
