The Grammy Awards may have scored 28 million viewers on Sunday night, but very few people noticed the moment when an intruder rushed the stage. The incident caused Jennifer Lopez to feel uncomfortable and/or annoyed.

Vitalli Sediuk, a known prankster on Ukraine TV, stormed the main stage where J-Lo was presenting Adele with the award for Best Pop Solo Performance. Dressed in a tuxedo and black glasses, Sediuk made his way to the microphone as the British singer was climbing the stairs. Lopez was then seen giving the man a stern look and, with a gesture of her thumb, made it clear he should vacate the stage.

He was hardly noticed by viewers.  Watch what happened here.
