The OnlyFans model who spent thousands of dollars on cosmetic surgery in a bid to look like Kim Kardashian died of a massive cardiac arrest after she got silicone injected in her buttocks by an 'unlicensed practitioner,' it has been revealed. Christina Ashten Gourkani, who went by Ashten G online, died at a California hospital last month while recovering from the operation. The 34-year-old American model's family and friends said that a "medical procedure took a turn for the worse" before her "sudden and tragic" death on April 20.
