Beyonce's dad just broke the biggest rule when it comes to birth announcements.

While several media outlets have reported Beyonce has given birth to her twins, the queen herself has so far stayed mum on social media.

But just because the 35-year-0ld singer and her husband Jay Z, 47, are yet to officially introduce their twin baby boy and girl to the world, doesn’t mean others aren’t celebrating their arrival.

Like Beyonce’s dad, Mathew Knowles, who posted a message for his brand new grand kids on Twitter and Instagram.

Knowles captioned the virtual birthday card (signed “Love, Grandad”) with the words “They’re Here!”, and added the hashtags #beyonce, #twins, #jayz and #happy birthday.

Not everyone is happy about the post however and several members of the Beyhive have accused the former Destiny’s Child manager of stealing his daughter’s thunder.

Earlier today, American celebrity news site TMZ has reported the now mum-of-three and her newborns are still in hospital where doctors are treating them for a “minor issue”.

Meanwhile, the world waits with Bey-ted breath the official announcement from Beyonce herself because if it’s anywhere near as over the top as her pregnancy announcement, it will certainly be something to behold.

And if they babies are anything like their 5-year-old big sister, Blue Ivy, they’ll be bloody adorable too.
