Kim Kardashian and Kanye West have named their baby daughter North West.

Sources close to the couple confirmed the decision, which comes five days after Kim welcomed her first child at a hospital in Los Angeles.

The revelation ends the intense speculation over the child's name, with other rumoured options said to include Kaidence Donda, in honour of Kanye's late mother.

And a source told UsWeekly that the couple have already given their daughter a nickname - she will be 'Nori for short'.

They added that the child has no middle name.

TMZ witnessed a signed birth certificate with the name North West signed by Kim, 32, and Kanye, 36, at Cedars-Sinai hospital.

People magazine confirmed the news with a source close to the Kardashian family.

The name North had previously been suggested as a possibility for the child, although many Kardashian fans had dismissed the idea as a joke.

And the revelation certainly proved fruitful amongst Twitter users, as North West began trending within minutes.

It also sparked a slew of jokes from would-be comedians amused by the choice.

Back in March, Kim denied rumours that Kanye wanted to name the baby North.

‘I do like Easton, Easton West,’ she joked on The Tonight Show with Jay Leno at the time.

Indeed prior to the baby's birth on Saturday it had been expected that the pair would continue the 'K' theme that runs in Kim's family - which is something that Kim has spoken about in the past.
