Kris' comments come after Khloe appeared alongside Kylie in her latest video on YouTube - with both of them covering their stomachs.
On Tuesday, Kris told Entertainment Tonight that she is "over the moon" for Khloe. "Just seeing her be able to do something so creative with [her denim line] Good American - that's her passion".
The momager, whose daughter Kylie Jenner is also reportedly pregnant, also opened up about how her brood cope with being working mums. "We seen her struggle to have a baby, just let it out enjoy and embrace it without having to worry about anything". As it's been said before, the devil works hard but Kris Jenner works harder.
"We totally vibe. "I don't care if I'm Kylie's older sister; I really respect that this is Kylie's business, and she built this business, so I think it's an honor to be a part of it", Khloe, 33, said". "I'm so proud of that kid".
Kris hasn't said much on Kylie's reported pregnancy in public.
In the video, the reality TV stars try on the 'In Love With the KoKo Kollection', introducing fans to each lippy shade.
Watch the moment at 4:29 below. And until those "babies" are actual babies and not lip kits, it's best not to jump to conclusions.
Although, Khloe and Kylie have yet to confirm their alleged pregnancies in the media, Kim did make the announcement that she and husband, Kanye West are expecting via surrogate.
