Beyoncé's mother, Tina Knowles, was a guest on Sherri Shepherd's show, where she got candid about how Beyoncé is backstage at her shows. 

Tina explained, "Oh my god. We laughed about this recently because I was saying, 'Girl, you get really mean back there.' And I am really happy that I don’t have to be back there anymore. She would say, 'I'm a [b****] in the morning,' and I'll be like, 'and the evening, too!'" 

Tina continued, "After we get off she'll say, 'Mama, I'm so sorry.' And I'm like, 'I know.' And certain times she'd be crying and I was like, 'She crying ’cause she knows she just said some crazy stuff to us.' But that’s the heat of the moment.

"Because you're trying to get your shoes on and everybody's waiting and, you know, if somebody's messing up — or they lose the shoes — then you messed up the whole show. So I understand it."
