Lady Gaga brought her concert in Washington, D.C. to a halt on Tuesday when she spotted two feuding fans in the audience.

The "Poker Face" hitmaker was finishing her performance of the song "Monster" when she spotted trouble breaking out in the crowd.

Pointing to the rowdy concertgoers, she called out, "Stop the music! Stop fighting! Do not fight at this show."

She then apologized to the audience for cutting short her track and made sure the venue's security guards had the situation under control before continuing with the show.

Concerned Gaga also asked about the welfare of the two fighting fans, adding, "Sorry, I just don't want you to fight. This is all about love and unity and happiness - no fighting."
