Calabasas, California - Fans believe that Kylie Jenner may have hinted towards the sex of her second baby.

Days ago, news broke that the young billionaire is expecting her second child with Travis Scott.

On Wednesday, Kylie's fanbase suspected she left subtle clues hinting whether she's having another girl or a boy.

The beauty mogul uploaded cute snaps of her three-year-old daughter, Stormi.

"My favorite girl," Kylie wrote, adding a blue heart emoji.

The adorable toddler struck various poses in the pics, but the 24-year-old's caption is what had internet sleuths guessing that she could be having a boy this time around.

While the vague description isn't much to go on, the little hint could still be a major clue.

Plus, Kylie also hasn't outright confirmed that she's expecting again, but the reality star kept her first pregnancy under wraps until Stormi was born.

Therefore, fans shouldn't expect Kylie to say too much right now if the news is true.

But the Keeping Up with the Kardashians star has been open about having more children.

According to Us Weekly, Travis and Kylie were apparently trying to conceive another baby for about year.

"She and Travis have been trying for many months … to get pregnant again. Kylie really wanted her siblings to be close in age because she feels so close to Kendall Jenner and wants that for Stormi," a source revealed to the outlet.

Kylie recently reunited with the rapper after the two split in 2019.
