A source tells PEOPLE the 20-year-old reality star and business mogul is due in February.
“They started telling friends a few weeks ago,” says the source.
“The family has known for quite some time. She is really excited and so is Travis!”
Another source close to the family tells PEOPLE:
“It is an unexpected but completely amazing turn of events that she could not be more excited or thrilled about.”
“Everyone is overjoyed for her,” says the source.
“This is the happiest she’s ever been.”
PEOPLE magazine reports Kylie’s reps did not respond to their request for comment.
Jenner has been dating 25-year-old rapper Travis Scott since earlier this year after splitting from her on-again, off-again boyfriend Tyga in April.
Another source told TMZ:
We’re told 20-year-old Kylie began telling friends earlier this month at the Day N Night Fest in Anaheim, CA.
Sources also say 25-year-old Travis Scott, Kylie’s boyfriend, has also been telling his friends. We’re even told — although we cannot verify — that he’s told friends they’re having a girl.
