Kanye West has a bigger wardrobe than Kim Kardashian West.

The 37-year-old rapper, who has 18-month-old daughter North, with his reality TV star wife, has reportedly had a new 15-feet-long walk-in closet installed in their $20 million mansion in Hidden Hills, California to store all of his designer clothes.

Despite having her own clothing line, the 'Keeping Up with the Kardashians' beauty's wardrobe measures almost three-feet less than the rapper's at just over 12 feet, according to Building and Safety Department records obtained by gossip website RadarOnline.com.

The couple, who got married in Italy last May, have also added a 23-feet-long dressing room to their new five-bedroom home, as well as a private spa room with a circular shower and bathtub, but the lavish property currently doesn't have a nursery for North.

The pair moved in with Kim's mother, Kris Jenner, shortly before North's birth in June 2013 in order to renovate an $11 million home in Bel Air.

But earlier this year they decided to put that property on the market and bought their Hidden Hills house, as they got fed up of waiting for the extensive work to be completed.

Kim recently revealed they are planning to move into their abode this month.

Asked what she is getting North for Christmas, she said: "It just got delivered so when we move in [to our new home], she'll see this new, fun play stuff that we got for her. We're going to show her on Christmas."
