Kim Kardashian is addicted to buying expensive designer clothes for her daughter.

The reality TV star welcomed her little girl, North West, into the world almost three months ago and has reportedly been shopping up a storm and spending thousands of dollars on her daughter's wardrobe while she works on getting her pre-baby body back.

A source told Star magazine: ''Kim ... spends all her time shopping online for Nori. She mostly buys white items, and she buys multiples of the same thing because they get dirty so easily.

''Many of the little designer dresses cost upwards of $600 apiece, and Kim will buy 10 to 15 items at once. Kim spends more on baby clothes a month than many celebrities spend on their house payments.''

Kim and her boyfriend Kanye West are especially fond of an $800 cashmere blanket made by Hermes and another source told OK! Magazine they ''buy them in bulk but they like them because they are super soft and Nori rubs them on her face all the time. At $800 [each], that gets really expensive!''

The 'Keeping Up with the Kardashians' star, 32, also allegedly spent $250,000 in Harrods in London in May on designer items for North before she was born.

The insider said: ''She got baby gear from Chloe and Christian Dior, Chanel booties and Versace rompers -- basically the best of the best.''

It was previously revealed that baby North already has more than 100 pairs of designer shoes.
