Fans are convinced Kylie Jenner is pregnant again after this Instagram post ...

It has almost been exactly one year to the day since Kylie Jenner dropped the bomb that not only was she pregnant for past nine months, but that she had also secretly given birth to her first child, Stomi, with her boyfriend, Travis Scott.

And now, the 21-year-old has sent her fans into a frenzy again after she posted a photo that hinted she could have ANOTHER baby on the way.

In the snap, the Keeping Up With the Kardashians star can be seen sitting on hardwood stairs while embracing her beau - which is surprising considering the mother-of-one doesn't usually share intimate photos of herself and Travis.

But what everyone is most shocked about is the caption.

With just two words, Kylie wrote: "baby #2?"

However, when one fan asked "are you pregnant?" in the comments.

Kylie replied: "No lol."

Rumours have been swirling since early January the makeup mogul is expecting her second child, after she took to Twitter to tease an "exciting" new project.

The young mum has never hidden the fact that she's keen for another baby.

Last October, she told fans she wanted to have another baby, adding, "but, 'When?' is the question and I'm definitely not ready right this second."

She also said she "definitely" wants another daughter, with a "really feminine name." 

We guess we'll have to wait to find out for sure!
