Notably absent were Kim's sister Khloe and Kourtney.

According to a new report, the Strong Looks Better Naked author was considered too low brow for the fancy shindig.

Khloe Kardashian the Good American designer was in Los Angeles with her daughter True, and so was Kourtney.

The two may also have been shooting scenes for Keeping Up With The Kardashians. Neither Khloe nor Kourtney have ever attended the Met Gala.

According to Radar Online, Khloe has been 'blacklisted' by host Anna Wintour of Vogue because she is too 'C list.'

And Kourtney would not attend in support of Khloe.

It may just be that Khloe is not there yet when it comes to high-end fashion. She also has not posed for Vogue yet, something Kim, Kylie and Kendall have done already.

Kylie and Kendall have also taken the cover for Teen Vogue, which curries favor with Anna it seems.

It appears as though many of the Met Gala guests have posed for the fashion bible - Gigi Hadid, Hailey Baldwin, Lady Gaga, Gwyneth Paltrow, Ashley Graham and Katy Perry, among others - and that may be one of the requisites.

Wintour is reportedly a bit snobby when it comes to the guest list.

DailyMail.com has reached out to Khloe's rep for comment.

Kim was the first family member to hit the high-profile event.

In 2013 she was West's plus one as she modeled a floral Givenchy gown while heavily pregnant with daughter North.
