Amid all the hoopla over the “birth” of The Chosen One, Solange Knowles, the sister of the new mom, whose name shall not be mentioned, went on a Twitter rant yesterday deploring the insensitivity towards her sister.

“It has really gotten out of hand. I’ve been doing my best at keeping my mouth shut….but the ignorance is really sad and upsetting,” she wrote in one of a series of tweets on her verified Twitter page.

We are supposed to be super human and watch people we love get slandered, lied on, and ridiculed. It is one of THE hardest things to accept. In any other workplace…if someone directly tells your mother or sister is a liar and a fake ect…you would naturally express yourself. However, the pure happiness and joy I’ve witnessed and experienced helps me to keep my mouth shut.

We hear that Solo’s anger was misdirected at her sister and brother-in-law, who refused to allow Solo to live tweet her niece’s birth — and who had the audacity to give fame whore Gwyneth Paltrow the honor of announcing the baby’s name to the world via a tweet!

Our very credible sources tell us Solange is “mad as hell” at her sister and brother-in-law for not giving her the privilege of announcing the baby’s name. But her sister reportedly told her she’ll get over it.
