A source told PEOPLE, 'She clearly made a conscious decision to step away from the spotlight. Kylie didn’t want her pregnancy to be a circus.
'She is actually very private about certain aspects of her personal life, and staying low key has given her time to really prepare for what's coming.'
The Keeping Up with the Kardashians star is reportedly expecting a baby girl in February with rapper boyfriend Travis Scott.
Kylie is yet to confirm her pregnancy publicly, although she has been keeping an incredibly low-profile, she has been spotted several times which has led fans to speculate.
