The Keeping Up With The Kardashians star will tie the knot with New Jersey Nets player Humphries in front of friends and family in Montecito, California tomorrow.
Perez Hilton unveiled the $300,000 (£181,000) waxwork at a ceremony on Thursday. The figurine is wearing a hand-made couture gown by Simin, who created three different dresses and invited the public to choose their favourite. The statue also wears a $1 million (£604,000) necklace by La Valencia.
Kardashian was immortalised in wax by Madame Tussauds New York last year, and admitted at the time she had been "nervous" about seeing her likeness for the first time.
She posted on her Twitter account last night: "Excited I just heard from @PerezHilton that Madame Tussaud is unveiling a new wax figure in Hollywood! Now there's 3 of us! 3some anyone LOL."
The Kourtney & Kim Take New York! star later posted her reaction to the waxwork's dress on her official website, writing: "Ummmm not quite what I would wear, but ok! LOL I honestly had no idea that they were doing this at Madame Tussauds until I saw it on Twitter!"
Kardashian's actual wedding dress has yet to be revealed although she has confirmed that she will be wearing a Vera Wang creation.
"Vera has been a close family friend for a long time and we had talked about this moment for years," she said earlier this month. "When it came to picking my wedding dress designer she was the first person I thought of. No one designs gowns the way she does!"
Tyra Banks recently said that she had offered Kardashian advice on choosing a silhouette "that the world isn't used to seeing her in", adding that the reality star had showed her some photographs of the final design.
She said: "What she showed me was so beautiful. It's interesting because they were pictures from a fitting, but it actually looked like the wedding, like her hair was done. So it was like a real almost dress rehearsal and she looked absolutely beautiful."
