The modest congratulatory gift is a straightforward 10-word shout-out to the new parents: “Congratulations Kim & Kanye, enjoy this beautiful moment together - Beyonce.”
The message is accompanied by a black-and-white photo of Kim and Kanye staring into each others’ eyes.
The couple themselves have kept silent in the wake of numerous reports that Kim gave birth to a girl over the weekend - about a month premature.
But her sister Khloe posted two tweets confirming the news:

Their mother Kris Jenner linked to both tweets on her Twitter account, then wished Kanye a Happy Father's Day, later posting a tribute to all the fathers in her family.
