Kendall Jenner has prompted outrage with a star-studded Halloween birthday party with over 100 maskless guests, breaking Los Angeles' strict rules about social gatherings amid the COVID-19 pandemic.
Public Health restrictions mean that residents should gather with only up to two other households, outdoors, with everyone wearing masks as well as keeping six feet (1.8m) apart.
Despite this, Kendall's 25th birthday celebrations saw stars like Justin Bieber, Jaden Smith, Paris Hilton and most of the Kardashian clan turn out. They donned costumes, but rarely any kind of face covering.
Guests partied in close proximity to one another at a rooftop venue in a Hollywood hotel, where 'no social media' notices instructed revellers to refrain from documenting the event online.
Of course, photos and videos made their way to Instagram regardless, infuriating fans who felt the rule-breaking bash was "irresponsible", "selfish" and "hypocritical".
"We love to see zero masks and everyone super crowded during a global pandemic," one Twitter user wrote sarcastically.
"Bitch, no wonder the USA is number one for COVID cases when shit like this is allowed to happen."
Entertainment Tonight reports that attendees were required to take a rapid COVID-19 test and return a negative result on site before entering the party.
"None of them distanced or wore masks and the Kardashians asked people to NOT POST PICTURES like you know what you’re doing is wrong!" said another.
"The amount of rage that I feel whenever I see pictures from Kendall Jenner's party. Celebrities need to start being wiped out cause there is no need for them," offered a third.
Many commenters took particular issue with the moment Kendall blew out the candles on her birthday cake, with seemingly little regard for the staffer holding it for her.
"OK Kendall Jenner blowing out candles as a masked waiter holds her cake and tries to move out of the way was actually the scariest thing I saw on Halloween," one tweet read.
"I can't sit in a lecture class but Kendall Jenner can blow on the cake everyone is going to eat," said another.
Others pointed out that celebrities like Kendall and many of her guests had frequently posted about the importance of wearing masks and following the rules.
"Celebs are too funny. They're the first to preach online about staying home and wearing a mask but then go to parties in Hollywood with 100s of people," one tweet read.
"I mean WTF... people are dying here," said another.
The backlash about Kendall's party comes hot off the heels of outrage over her older half-sister Kim Kardashian's birthday celebrations, which saw her fly her "inner circle" to a private island getaway.
