Listen to Lady Gaga on iHeartRadio

A reminder that Lady Gaga is a pro....

At a concert at the House of Blues in New Orleans, Lady Gaga was performing her first huge hit and Lady G classic "Just Dance," when unexpectedly her sound board went out. Luckily, a fan caught the whole thing on video.

Instead of freaking out, Mother Monster once again proves she is extremely talented and continues performing as if nothing happened. She sang "Just Dance" a cappella as the crowd joined in too to help her out. Eventually the board comes back into play, but she obviously didn't even need it!
