Gomez says paramedics were called to the hotel, but Kardashian refused medical treatment.
He says Kardashian returned to her room, removed the powder from her hair and clothing and returned to the event.
"That probably is the craziest, unexpected, weird thing that ever happened to me," the reality star told E! after the incident. "Like I said to my makeup artist, I wanted more powder and that's a whole lot of translucent powder right there."
And although the woman could be heard yelling what sounds like "Fur hag!" in the video, PETA denied any involvement in the incident, according to Gossip Cop. "PETA has tried everything from polite letters to public protests, but Kim Kardashian has not been moved by the news that animals are beaten, electrocuted, and even skinned alive for real fur garments,” a PETA rep told Gossip Cop in a statement. “Whoever threw that flour may reach her when our polite appeals did not.”
