Kanye West broke into tears last night when attempting to perform the song "Hey Mama" at a concert in Paris.

Members of the audience told PEOPLE that Kanye had dedicated the song to his mother and began to start performing -- when he suddenly became overwhelmed with emotion. One audience member told the mag, "A back-up singer, the DJ and a guitar player came over to console him. It looked like he might collapse. He just couldn't continue. He just stood there in a spotlight, crying while the band continued playing."

West left the stage, but eventually returned to perform the song "Stronger" with the audience yelling out their support. He is expected to return to the U.S. for his mother's Tuesday funeral in Oklahoma City.
