Kylie Jenner waiting to find out sex of baby No. 2

Call off the internet sleuths.

Kylie Jenner revealed during Vogue’s “73 Questions” that even she doesn’t know the sex of her second child — despite fans being convinced she’s having a boy.

“Well, we need to find out the gender first,” when asked if she’s picked out a name for the baby, “and we decided to wait.”

The Kylie Cosmetics founder set the internet ablaze this week after she posted a photo of her and daughter Stormi wearing all blue to promote the launch of her new line Kylie Baby.

“Someone’s having a boy!💙💙💙,” commented one follower.

“She’s obviously going to have a boy cause of the blue,” wrote another.

“I feel like she will have a baby boy,” speculated another.

Many fans believe the blue-themed photoshoot was the second clue that the Kylie Swim designer, 24, is having a boy.

Back in August, Kylie captioned a photo of Stormi “favorite girl,” with a blue heart emoji.

The former “Keeping Up With the Kardashians” star confirmed her pregnancy weeks after Page Six exclusively broke the news in August that she was pregnant again with Travis Scott.

We were told at the time that the entire Kardashian-Jenner family was “thrilled.”

Kylie’s sister Kendall explained Kylie’s direct reveal strategy last week: “She called me, and I answered the phone, and she just had her little sonogram.”

Jenner and Scott announced the arrival of their daughter Stormi in February 2018 after keeping the pregnancy a secret.
