It looks like Khloé Kardashian just made a cryptic pregnancy announcement

As we've previously discussed, three of the Kardashians are reportedly pregnant.

Kim is expecting a third child with rapper Kanye West, Kylie and her partner rapper Travis Scott are reportedly expecting a child in January or February, and our protagonist Khloé, and her partner Tristan Thompson, a Canadian basketball player for the Cleveland Cavaliers, are also reportedly expecting a child.

On the reality show Keeping Up with the Kardashians, Khloé said:

He wants to have about five or six kids with me and that’s lovely.

We could start at one and we could grow from there.

The latest evidence to support the pregnancy conspiracy comes from Khloé's Instagram:

In response to the snap, her boyfriend Tristan Thompson, commented:

To which Khloé replied, crucially:

Obviously, this could just be a use of the romantic (and controversial) pet name 'daddy', or it could be the pregnancy confirmation that fans have been waiting for.

Way back in June, TMZreported the pair had captioned themselves on polaroids:

Dad + Mom

The photos were taken for her surprise 33rd birthday party.

Recently Khloé has posted about the coupling on Instagram, captioning a kiss:

The day I met you, my life changed. Thank you my love!

The couple has been the centre of pregnancy rumours since September when a source close to the couple told People that Khloé was pregnant.

BuzzFeed reported in September that "a source with knowledge of the situation" confirmed the pregnancy to the outlet.

There has been no official announcement yet.
