Washington, July 18 (ANI): Kourtney Kardashian and her boyfriend Scott Disick made a last-minute decision on their daughter's name after she was born on July 8.

According to a source, the pair had originally planned on naming their baby girl Mila-but switched to Penelope Scotland Disick.

Despite the unexpected name swap, the birth was relaxed and easy, a family source said.

He was really supportive. He may be an ass at times, but he comes through for the big stuff, Us magazine quoted the source as saying of Disick.
