Beyonce and husband Jay-Z are proud parents of a baby girl called Blue Ivy.
According to the Daily Mail, the 30-year-old singer had an elective caesarean in New York on Saturday night.
Reports first emerged claiming the couple had called their baby Ivy Blue Carter. But then on Twitter rumours started that her name was round the other way – Blue Ivy or even Blu Ivy.
It took A-list friend Gwyneth Paltrow to sort it all out, when she tweeted a gushing, “Welcome to the world Blue! We love you already.”
She then confirmed to a fan asking if it was Ivy Blue or Blue Ivy, that it was indeed “Blue Ivy Carter”.
Sister Solange helped to explain the mystery of the reversed name when she tweeted, “information that goes through the telephone always gets delivered wrong.”
Baby Blue has already had lots of celebrity welcome tweets including Rhianna who posted, “’Welcome to the world princess Carter! Love Aunty Rih.”
Did you know? Beyonce and Jay-Z are not the only celebs to call their baby Blue. U2 guitarist The Edge named his daughter Blue Angel, while Alicia Silverstone named her newborn daughter Bear Blu last May.
