Now, Kylie's mom Kris Jenner is speaking out for the first time since the news broke, People magazine reports.
Attending the Versace show in Milan Friday to support her daughter Kendall Jenner, Kris told The Cut, "You never know what is going to break at any moment."
She didn't address Kylie's pregnancy specifically, but also said that "something happens every day."
Kris looked stunning in an all-black ensemble made up of a sequined jumpsuit and shades. She was front-row at the show.
Sources told People the pregnancy is not a mere rumor, saying, "It is an unexpected but completely amazing turn of events that [Kylie] could not be more excited or thrilled about."
