MUM’S THE WORDCaitlyn Jenner WAS told about Kylie’s pregnancy as reps for the star confirm baby rumours for the first time

The source added that reality star Caitlyn would have preferred for Kylie to wait until she was older to have a baby.

"Caitlyn is concerned that Kylie and Travis really haven't been dating very long, and that a baby will put a big strain on their relationship, but Kylie believes the opposite - that she and Travis will be together forever."

Reports last week revealed the news with a source telling People magazine.

“It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about.

"Everyone is overjoyed for her. This is the happiest she’s ever been.”
