We know Kanye chose the name to honour his home-town, and that Chicago will be called Chi (pronounced SHY) for short, as confirmed by her aunty, Khloé Kardashian. And, now, we know her full legal name, too.
Chicago's birth certificate has been leaked, with The Daily Mail reporting that she was born at 12:47 am on January 15th and she weighed seven pounds and six ounces at birth. You can see the document here.
The document also shows that Chicago's middle name is... nothing! Just like her big brother and sister, Chicago will exist sans middle name.
With names like Chicago, Saint and North, we guess you don't *really* need a middle name.
