Grandpa accidentally broke the news with a Tweet congratulating Queen B on the birth of twins — a boy and a girl.
The businessman, 65, celebrated the babies’ arrival by posting a balloon-covered birthday card to Instagram on Sunday, June 18. “Happy Birthday to the twins! Love, Granddad,” the card read. Knowles captioned the post, “They’re here! #beyonce #jayz #twins #birthday #happy birthday.”
Speculation was already rampant after extra security was added at UCLA Hospital. Congrats!
