She probably didn't mean to slight her other two children—North and Saint--by husband Kanye West, but it's clear that the girl born through major medical means is particularly dear to the Keeping Up with the Kardashians star.
After a fan on Twitter asked Kim for an update on the newborn on Feb. 24, she wrote back, "The sweetest! Best baby!"
Kim, 37, went on about Chicago, "She looks a bit like North and a tiny bit like Saint but definitely her own person!"
Chicago came into the world on Jan. 15, and Kim announced the birth via her app on January 16.
"Kanye and I are happy to announce the arrival of our healthy, beautiful baby girl," she wrote.
"We are incredibly grateful to our surrogate who made our dreams come true with the greatest gift one could give and to our wonderful doctors and nurses for their special care. North and Saint are especially thrilled to welcome their baby sister."
As RadarOnline.com revealed, however, sources said millionaire Kim paid the surrogate mother less than $70,000 for bearing Chicago!
Kim showed off Chicago in sister Kylie's birth reveal on Feb. 4 of her baby, Stormi, with rapper beau Travis Scott.
According to a Radar source, Kim wants to be the one to tell Chicago first that she was born to a surrogate mother. But Kanye doesn't agree with that, the insider said.
