Kylie Jenner is currently expecting her second child, and she recently revealed she’s experiencing a common symptom – pregnancy brain.

Posting to her Instagram Story, the makeup mogul shared a video of herself and older sister Kendall Jenner making a stop at Starbucks. The video begins with Kylie showing off her baby bump in a black spandex outfit before turning the camera on her sister.

"My sister came to get me, to come with me to get Starbucks," Kylie can be heard saying from behind the camera, Entertainment Tonight reports.

“Are you okay?” Kendall responds, to which Kylie replies, “No! I have pregnancy brain, I can’t get it together. But she came with me to get Starbucks.” Kylie ended the video with a glimpse of her pink drink.

Many women report experiencing pregnancy brain while expecting, which is characterized by forgetfulness. WebMD explains that while pregnancy doesn’t alter a person’s brain, the stress that comes with it can contribute to memory loss. The outlet notes that being busy, multitasking, and not getting enough sleep while pregnant also play a part.

Some research suggests that shifting hormone levels – there are 15 to 40 times more progesterone and estrogen being produced by the body in pregnancy – also affect spatial memory.

Kylie confirmed her second pregnancy in September after several weeks of speculation. She shared a 1-minute video showing Kylie discovering she’s expecting and telling her loved ones, including her on-and-off boyfriend Travis Scott.

The couple were first romantically linked in 2017 and went on to welcome their daughter Stormi in February 2018. Kylie declined to confirm she was even pregnant until after Stormi’s birth. However, she’s been much more open about her current pregnancy.

Reports suggest the couple’s second pregnancy was very much planned. Our source told Us Weekly in August that they’d been trying “for months" to get pregnant, adding Kylie wants her kids to be close in age. A different source said they’ve been planning for baby no. 2 for years.

Kylie’s second pregnancy isn’t the only thing keeping her busy. The reality star recently launched two new businesses – her swimwear line, Kylie Swim, and a baby product brand, Kylie Baby, which so far has released a line of skincare products for infants and toddlers. The products are advertised as being vegan and hypoallergenic.

It’s suspected that Kylie Baby will eventually expand to include even more children’s products, like furniture, strollers, blankets, and other accessories. However, mum is the word on Kylie’s business plans as well as when her second child is due.
