On Wednesday night, Beyoncé Knowles took to Instagram to announce that she was pregnant — not with one child but with twins. In the photo, she's veiled and kneeling in front of a bouquet of flowers, gently clasping her stomach; in the caption, written on behalf of her and her husband Jay-Z, she said that they "have been blessed two times over" and "are incredibly grateful that our family will be growing by two." The photo has blown up, inevitably. Within eight hours, it had accrued more than 6.6 million likes — more than any photo ever posted to Instagram, Billboard。
