But when Kim and Kourtney learned that Khloe was in labor, the Kardashian sisters flew to be by her side and acted as if "nothing had happened", said one of the insiders.
Stormi Webster isn't the newest Kardashian/Jenner anymore, but her baby pics are still cute as.
Her mum, Kris Jenner has confirmed the birth of Khloe's baby girl on Instagram.
Perhaps, that's what made Kim delete the photos from her social-media page.
"I think you should", a friend answered.
However, the pictures were mysteriously deleted, as followers inundated the comments section with queries as to why Kim was posting holiday pictures while her sister Khloe dealt with reports that Tristan Thompson had cheated.More news: Delhi Daredevils beat Mumbai Indians by seven wickets in IPL match

In another tweet, the reality TV star, who welcomed baby girl Chicago back in January, bragged that Khloe's new baby is "so gorgeous", and that she " can't wait for our baby girls to grow up as best friends the way we are".
The Kardashian sisters reportedly felt "sick" at having to be polite to Tristan.
"Tristan is so emotional right now. This will be fun, guys!" she said in a video.
"He has commissioned a stunning diamond necklace and matching bracelet for Khloe, and a mini version of the bracelet for their princess", the insider adds.
