Ella Ruby Ginn, who has appeared on the current series of Take Me Out, says she has been obsessed with vinegar ever since she was a little girl.
And now, the 19-year-old claims she drinks two bottles a week.
She's so addicted to the brown, acidic stuff that she keeps sachets in her bag in case she gets cravings.
While she used to gulp down endless bottles of malt vinegar, she's recently switched to apple cider vinegar as it apparently aids weight loss.
Experts say there hasn't been much research into the effects vinegar can have on your health, but because it contains so much acid it's likely to cause dental erosion.
She told the Daily Star: "It's really sour but I love it. My favourite bit is when it burns in my chest."
