Check out Khloé's Jenner siblings and Kylie's boyfriend Travis Scott arrive on the red carpet HERE:
Soon-to-be parents of four Kim Kardashian and Kanye West are famously close with Anna and her team, gracing the cover of Vogue as a couple with their infant daughter North West back in 2014.
Just weeks ago, the reality star turned beauty mogul appeared on another Vogue front cover, this time with children North, Saint and Chicago.
An insider told RadarOnline that Kim would "never want her Kardashian sisters there because that would take the attention away from her".
But whether the aspiring lawyer likes it or not, Kim's elder sister Kourtney Kardashian is said to have been invited to this year's Met Gala - but opted to stay in Los Angeles as a show of support for Khloé.
"Khloé and Kourtney have never been invited to the Met Gala, but Kourtney was invited to this one and chose to stay home with Khloé because she didn't want to leave her alone," the source said.
But Khloé need not lick her wounds for too long, because if history repeats itself she could easily find herself on the guest list for Met 2020.
According to Grazia, KKW herself was "banned" from the event by Anna Wintour back in 2012, but just one year later attended as then-fiancé Kanye's date when he acted as the evening's headline performer.
For their Met Gala looks, reality star sisters supermodel Kendall Jenner and billionaire business mogul Kylie Jenner wore contrasting orange and purple Versace gowns.
Mum Kris Jenner rocked a navy jumpsuit and elaborate grey coat from Tommy Hilfiger, while Kim K said she was "honoured" to wear a custom Mugler corset dress inspired by Sophia Loren walking out of the ocean.
Start planning your look for next year, Khloé, we're all behind you!
