NEW YORK, New York (X17online) - Kourtney Kardashian showed off baby bump in a flowy black dress, as she stepped out in New York City with her sister Khloe last night.

Yesterday, the eldest Kardashian sister announced that her on-again/off-again boyfriend Scott Disick is the father of the baby she is expecting in December.

Kourtney also said the pregnancy was unplanned because she forgot to take her birth control pill. However Kourtney claims that both she and the baby's father are excited and happy about the new addition to the family.
