A celebrity PR expert spoke to The Mirror and suggested that the presence of "two controversial celebrities" would bring attention to the prestigious event. The expert, Matt Yanofsky, highlighted that both Markle and Kardashian are known for their controversial reputations and are famous for being famous. He argued that their attendance would guarantee press attention, which in turn would generate revenue for advertisers.
Yanofsky further speculated that Kardashian would likely make a splash on the red carpet, given her history of attention-grabbing outfits. He also noted that Anna Wintour, the editor of Vogue, likely invited the controversial celebrities in order to draw attention to the event and generate revenue through sponsorships.
The Met Gala is known for its high-end fashion and attracts many A-list celebrities. Yanofsky explained that while Vogue is a prestigious outlet, it still needs to generate news coverage in order to attract advertisers. He pointed out that Wintour has a history of using celebrities to draw attention to her products, as seen when she put them on the cover of Vogue in the 1980s.
Overall, it seems that Markle and Kardashian's attendance at the Met Gala will likely generate significant media attention and revenue for advertisers.
