It's a KarJenner baby boom!

Kylie Jenner is pregnant and boyfriend Travis Scott is the dad, DailyMail reports. Apparently, the reality star let the secret slip at the Day N Night Festival in Anaheim, California, earlier this month, and the rapper has been slowly telling his own pals. The couple are allegedly expecting a baby girl!

If this comes as a surprise, that's because the LipKit queen has been posting old pics to her social media, and the more recent ones have been from the chest up only. "She has been looking pregnant for about four months,” a source dished to Page Six.

The pair have been dating since April, shortly after she broke things off with longtime boyfriend Tyga.

The family is expected to make a formal announcement later today. Wow!
