Porn star Gigi Dior trademarked her stage name last year, which was approved on September 20, 2022. Performers trademarking their stage names is common. They do it to protect against people pretending to be them. Trademarks allow for a level of protection that copyright laws don’t always cover.

Now fancy French fashion house Christian Dior Couture has filed a legal claim asking to overturn the trademark, saying she is damaging its business.

“This is ridiculous, my name has nothing to do with couture, and — the funny part is — what I do usually involves wearing no clothes at all,” Gigi told Page Six in response to the lawsuit.

She uses the name stage name (Gigi Dior) on her personal website, her OnlyFans account, her webcam work, and all social media accounts.

But Paris-based Christian Dior Couture sniffed in the filing, “All goods and services … are opposed, namely: Entertainment services … personal appearances by a porn star … providing a website featuring non-downloadable adult-themed photographs and videos.”

The fashion house states its grounds for opposing Gigi’s trademark: “Priority and likelihood of confusion, dilution by blurring and dilution by tarnishment.”

Gigi has appeared in seven porn flicks and many online videos, including “Horny Hiking.” She also does webcamming and has been nominated for “Milf of the Year” by the Cam Awards.

“I trademarked my stage name for entertainment and modeling purposes, I had to show proof of what I was using the name for, so I used appearances at exotica, and a website for confirmation … My request was granted,” Gigi said.

“A couple of weeks ago, on Oct. 18, I received notice from Christian Dior Couture that they were appealing my trademark approval and they claim that the name Dior is being diluted and that I am diluting their products.”

She has until Nov. 17 to present a written response against Christian Dior Couture’s appeal. If not, her trademark would be overturned.

Gigi, who has been in the adult industry for just two years, said she applied for the trademark to prevent others from ripping off her brand.

The former New York model and actress, who is a single mom with four kids under age 12, said, “If I lose my name, I have built a brand around this name, it has become me and my reputation, so it’s really devastating to think I might have to start from scratch and rebrand everything.

“I have thousands and thousands of T-shirts, signs, and photographs. I have retained websites, and all of my social media. I’d have to start again, it’s going to be a huge undertaking if I lose this name.

“I’m devastated, and it is ridiculous.”

Gigi also wrote on Twitter, “This is the face you make when you learn that a company with over 50 billion dollars in revenue took legal action against you … PLEASE RETWEET THIS. I need to spread the word … CHRISTIAN DIOR is appealing my APPROVED US Patent and Trademark on my name Gigi Dior.”
