SO it has finally happened. Beyonce Knowles and Jay Z have welcomed their first child together – a daughter.

* Congratulations! *

NY Daily News reports that the singer had checked into the Lenox Hill Hospital in New York under the pseudonym Ingrid Jackson, and gave birth on Saturday. Both mommy and baby are reportedly doing just fine.

Keeping in with Hollywood’s current tradition of giving odd names to celebrity babies, Bey and Jay have also chosen a unique moniker for their newborn child – Blue Ivy Carter. Yup, seriously.

Fans were earlier confused as to whether the child was called Blue Ivy or Ivy Blue, and one of Beyonce’s celebrity friend helped to clear the confusion.

More tweets started to flow in from fellow celebrities, congratulating the new parents on their bundle of joy.

Long time friend Russell Simmons also wrote: “congrats to my good friends Beyonce and Jay-Z.”

Sharm says: Now there is only one thing left to do…to wait and see whose looks the baby has inherited. Let it be Beyonce’s *fingers crossed*
