Kanye West and Kim Kardashian welcomed a baby girl on Saturday (June 15).

Source close to KK say it was a natural child birth. She started having contractions Friday night and went into full labor early Saturday AM.

The baby and Kim are both in good health. We’re told Kim delivered the baby at Cedars-Sinai Medical Center 5 weeks early.

Kanye West was there for the entire thing — in the delivery room by Kim’s side. We’re told Kanye cancelled his appearance at his own record release party last night when Kim told him she was feeling “a little off.”

It is the first child for Kim and Kanye.
