The latest information about the potentially pregnant star comes courtesy of TMZ, the publication that initially broke the story.
Sources told the site that the mum-to-be has already filled a closet with high-end threads for her baby, spending a whopping $70,000 ($89,551AUD) on clothing and accessories for her bub.
“This is going to be the best dressed kid you’ve ever seen,” a source told the site.
Kylie and Travis were reported to be expecting just over one week ago.
"They started telling friends a few weeks ago,” a source told PEOPLE last week. “The family has known for quite some time. She is really excited and so is Travis!"
"It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about.”
