Kim Kardashian West has reportedly forked out a whopping $550,000 on a lavish nursery and baby goods.

The 37-year-old reality star and her husband Kanye West are currently expecting their third child, who will be born via surrogate mother, and it has now been claimed they have spared no expense when it comes to making sure the new arrival is fully catered for.

According to sources, Kim and her 40-year-old spouse - with whom she already has North, four, and Saint, two - have splashed the cash on goods including a Swarovski-encrusted rocking horse and a $170,000 teddy bear.

It has also been claimed the 'Keeping Up with the Kardashians' star has had items including a luxurious velvet crib by designer Dolce Notte, as well as a hand-painted cradle, a silk bassinet and matching wardrobe and chair - reportedly amounting to another $40,000 - imported from Italy.

A source said: ''Kim's also hand-sourced some of the world's most expensive toys for her newborn, including a $137,000 Swarovski-covered rocking horse, a $170,000 Steiff Louis Vuitton teddy bear and a limited edition Suommo Dodo solid gold dummy costing $96,000.''

Kim is also believed to have gotten her hands on a number of designer and diamond-encrusted toys for her little girl, and sources claim even Kanye has told her to scale back her spending.

They added to Closer magazine: ''Even Kanye's told her to stop spending as she's out of control!''

It comes after it was claimed last week that Kim and Kanye's surrogate is set to give birth ''any day now'', and the couple ''can't wait to bring their baby home''.

Their decision to go through a surrogate for their third child came after Kim suffered complications with her two pregnancies, experiencing early-onset preeclampsia with North and further troubles during labour with Saint.
