Kim Kardashian has sparked fresh interest in celebrity autographs after appearing to sign another fan's Hermès Birkin bag. The moment was captured at the Mexico City premiere of All's Fair, where a fan showed off a black handbag while standing beside the reality star.
The encounter follows another Birkin signing moment involving Kardashian in Shanghai. Her latest interaction raises a fun question for luxury fashion fans: could celebrity signatures become the next way to make a designer bag more personal?
Another Birkin Moment
In the video, a woman holds up a black Hermès Birkin with gold-coloured locks and hardware. Kardashian stands beside her in a white outfit as the fan shows the bag to the camera. The handbag has a structured shape, two top handles and metal details that make it stand out.

The woman appears excited as she presents the bag, while Kardashian remains close by during the encounter. The clip suggests that the fan wanted to keep a special memory of meeting the star. However, the available footage does not clearly confirm when the autograph was added or show the full signing process.
The video also raises questions about how fans choose to mark their luxury items. Some may prefer a classic bag with no extra marks, while others could see a celebrity's signature as a personal touch. For this fan, the moment offered a chance to share an unusual fashion story with others.
Why Birkin Bags Matter
Hermès Birkin bags are known for their luxury status, careful design and high prices. They come in different sizes, colours, and materials, with some rare versions attracting strong collector interest. Their appeal makes adding a celebrity's signature especially interesting.
Unlike a signed photo, writing on a handbag changes the item itself. A fan may see the autograph as a special memory, while another owner may prefer to keep the bag free from marks. The choice depends on personal taste and what the owner wants from the item.
The bag's value also depends on factors such as its condition, rarity, materials and demand among buyers. A famous person's signature does not automatically make a designer item worth more money. Any claim that Kardashian's autograph raises a Birkin's resale price would need evidence from actual sales or a qualified expert.
From Shanghai to Mexico
Kardashian's latest Birkin moment follows another fan encounter in Shanghai in September 2026. During that visit, she was asked to sign a red crocodile Hermès Birkin using a gold marker. She seemed unsure about writing on such an expensive item before agreeing.

During the Shanghai encounter, Kardashian reportedly joked that signing the bag felt 'illegal' and 'blasphemous'. The fan wanted her name written on the front, and she agreed after checking that this was what he wanted. The pair then posed for photos together.
The earlier moment drew attention because Birkin bags are known for their high prices and strong appeal among luxury shoppers. Some people online wondered whether Kardashian's signature could make the bag more special, while others questioned whether it was wise to write on it. No confirmed sale shows that her autograph increased its value.
Could Signatures Become Trendy?
A celebrity autograph can turn a meeting into a memory that a fan keeps for years. Signing a luxury handbag, however, is different from signing a photo or a piece of paper because it changes the item itself. That makes the choice more personal for anyone who owns an expensive designer bag.
For some collectors, a signed bag may be more appealing because it directly links to a famous person. Others may prefer to keep their designer bags in their original state, especially if they plan to sell them later. Without a sale or expert review, it's impossible to say whether a signature adds to a Birkin's market price.
Kardashian's recent encounters have put an unusual idea in the spotlight. Fans are used to asking stars for photos and autographs, but a designer handbag offers a different place to keep a memory. Whether more fans will follow this example remains to be seen.
