Bebe Rexha went in on an audience who didn't sing along to one of her songs. She performed at a pre-Grammy event on Thursday night. When she performed the hit Meant To Be and the crowd didn't join in, Rexha lashed out. She told the band to stop performing and said, "This song was No. 1 for 50 (expletive) weeks. I work too (expletive) hard for this (expletive), OK?" Rexha got the sign to chill out from her mother who was in attendance. Rexha then told the audience, "My mom is like ‘please calm down.’ I love you mom. I’m calming down.” Have you ever had an artist go off on an audience at a concert? What was it for?
