Kim Kardashian's daughter 'looks just like her'

The Kardashian klan is one tiny person bigger now that reality queen Kim has given birth to her first child almost five weeks early.

The baby girl, whose arrival was heralded on Twitter (of course), arrived so suddenly that father Kanye West had to skip out on his own album release party for "Yeezus," which officially debuts Tuesday.

Although the tiniest Kardashian's name hasn't yet been revealed, a source said the baby girl has dark hair and "she looks just like Kim."

And as if anyone doubted, when the name is made public, "it will start with a K."

I can not even begin 2describe the miracle that is now apart of our family. Mommy/baby are healthy &resting. We appreciate all of the love.
