TMZ spotted Kat at Avalon last night, and while signing autographs she told our photog, "It was an obvious case of forgery."
On her MySpace page, Kat wrote a long blog post that said, in part, "The first time I saw the actual photo with the writing on it, I almost puked, considering, those are things I would NEVER even think about, let alone write!"
As TMZ reported, Ami James (Kat's former boss on "Miami Ink") received a photo with a swastika and a flaming Star of David that was allegedly written by Kat. She denies it, and TLC, which airs "LA Ink," is standing by her.
