Suki Waterhouse once joked about washing her hair with soda because she was "bored" during an interview.
As part of a chat for Us Weekly published in 2015, the British star revealed that she rinses her blonde locks with Coca-Cola.
"I rinse my hair with Coca-Cola sometimes," she told the publication. "I don't like my hair when it's washed - it's fine and limp - but Coca-Cola makes it tousled, like I've gone through the Amazon or something."
On Friday, a fan took to Twitter to ask Suki whether she still prefers soda over shampoo.
Accordingly, Suki decided it was time to come clean and share the truth.
"Ok.. i have to be honest, i got bored doing hair interviews and said this. i have never done this ma'am (sic)," she posted.
Later, Suki also uploaded a screengrab of a Bustle article written by Jessica Booth in which she described how she washed her strands with Coca-Cola.
"I did Jessica dirty," the 30-year-old confessed.
