Kylie Jenner announces she's pregnant with second child in Instagram video

Beauty mogul and socialite Kylie Jenner announced Tuesday on Instagram that she is pregnant with her second child. The 24-year-old is already a mother to 3-year-old Stormi Webster.

The minute and a half-long Instagram video — which is captioned with a heart emoji, a pregnant belly emoji, and @travisscott — begins with what appears to be a positive pregnancy test. It then shows her and boyfriend Travis Scott, 30, taking their daughter to the doctor's office for Jenner's ultrasound. Also featured is what appears to be the moment Kylie tells her mother, Kris Jenner, she is pregnant. Webster gives her grandmother an envelope with photos of an ultrasound.
