TMZ is reporting that the 20-year-old started telling friends earlier this month, with her boyfriend, rapper Travis Scott, apparently telling friends that they're expecting a girl.
Another source close to the famous couple told People: “It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about.”
This speculation came to a head when Kylie posted a photo on her Snapchat that appears to show a bump under her shirt, with others noting that she hasn't made many public appearances recently.
TMZ also noticed that the social media star's recent Instagram photos are either old, or only show her from the chest up.
Now to wait for official confirmation (or not) from the Kardashian family...
