The reality star has only been spotted out a handful of times over the last few months nbut this sighting has proved that she might have already become a mum.
Kylie was dressed in a black tracksuit and she did not look as big as she has been looking the last few weeks leading to speculation that she has popped.
Kylie was at a construction site with her mother Kris Jenner and her best friend Jordyn Woods.
Her apparent due dates February so maybe she had the baby early??
