The 22-year-old model did make it in time for the event's dinner, alongside friends Bella Hadid and Winnie Harlow.
Lately, Jenner has been opening up more and more about her debilitating anxiety.
Talking to Harper's Bazaar, the Keeping Up With The Kardashians star spoke about just how badly it affects her life.
'Where do I even start? Everything is so horrible,' the 22-year-old model confessed to the publication.
'I have such debilitating anxiety because of everything going on that I literally wake up in the middle of the night with full-on panic attacks.'
Jenner also explains that the 'constant negativity' that surrounds her life has a major impact on her health.
'It’s hard not to get eaten alive by all the negativity,' she admits.
In a previous episode of Keeping Up With The Kardashians, Jenner has revealed that she suffers from serious sleep paralysis that leaves her 'scared to fall asleep.'
