Spotted for the first time out and about in public in months, TMZ obtained photographs and video of the 20-year-old and her growing bump.
In the images, Kylie wears head-to-toe black clothing, walking along side her mum Kris Jenner and BFF Jordyn Woods.
TMZ are reporting this is the first time Kylie has been spotted in public since September.
The Life of Kylie star, who is expecting her first child with boyfriend Travis Scott, made a clear decision to keep her pregnancy private from the start.
"Kylie didn’t want her pregnancy to be a circus,” a source previously told PEOPLE.
On Monday, Calvin Klein unveiled an ad featuring Kylie and all four of her sisters — Kendall Jenner, Kim Kardashian West, Kourtney Kardashian and fellow mum-to-be Khloé Kardashian — posing for the campaign.
In the advertisement, Kylie conceals her baby bump underneath a red-and-white quilt, as the rest of her sisters lie on top of it.
