Celebrity Number Six (sometimes abbreviated C6^[1]) is the name given to a previously unidentified face on a fabric print, the subject of a years-long lost media mystery. In 2020, Reddit user TontsaH posted to the subreddit r/TipOfMyTongue asking for help in identifying eight faces depicted on a set of curtains. While seven were quickly identified as actors and models prominent in the mid-2000s, one – the sixth, as numbered by TontsaH – proved far more difficult to identify, leading to the creation of a dedicated subreddit.

The subreddit's members pursued hundreds of ultimately fruitless leads for four years, including contacting the fabric's supplier, reviewing a decade's worth of photos on Getty Images taken by the photographers of the other seven images, and various forms of image manipulation and reverse image searching. In 2024, Redditor StefanMorse identified Spanish model Leticia Sardá as a likely candidate by running a colored-in version of the print through the facial recognition tool PimEyes. On 8 September, user IndigoRoom posted the original photo, taken by Leandre Escorsell in 2006; IndigoRoom had contacted Escorsell because he was known to have photographed Sardá. The next day, Sardá, who had retired from modeling in 2009, posted a picture of herself holding the image. She has since sold copies of the image and resumed modeling.

The successful identification was one of several lost media mysteries solved in 2024, including the origins of the songs "Ulterior Motives" and "Subways of Your Mind", and the original Backrooms image. There was initially a dispute among the subreddit's members as to whether IndigoRoom's post was a hoax perpetrated using generative artificial intelligence. Commentators discussed how AI both made the find and others like it possible and, through increasingly plausible deepfakes, could hinder the solving of similar mysteries in the future.
