Beyonce and Jay Z are said to not have reacted to Solange's attempted elevator attack because they're ''used to'' her hot-headed nature.
The A-list couple appeared totally unfazed in footage obtained by TMZ showing Beyonce's younger sister Solange viciously lashing out at her brother-in-law in an elevator at the Met Gala afterparty, held at New York's Standard Hotel last week, and sources now claim it's because the superstars are used to her tantrums.
An insider told Us Weekly magazine: ''Solange has flipped her lid like that before. She is genuinely a sweet and nice person but she also keeps s**t real.
''She can take a small thing and it triggers her.This is not the first time this has happened.
''That's why Bey and Jay were so calm. They are used to this from Solange. It has definitely happened before.''
After the bust-up, during which Beyonce remained completely impassive, Solange left in one car with her sister, while Jay Z left in another and insiders say it was typical of the 'Crazy in Love' singer's ''calm'' nature to try and keep the peace.
The source explained: ''It is a testament to Beyonce's calm nature how she kept back and played the peacekeeper here. She is so calm and always the peacekeeper.''
The incident has sent the internet into a frenzy, with hundreds of memes poking fun of the situation popping up online and someone even changing Solange's 'occupation' on her Wikipedia page to ''Jay Z's 100th problem''.
