Suki Waterhouse drinks vinegar every morning.
The 24-year-old beauty admits her friends think her daily ritual is "disgusting" but she believes the special drink she makes with the acidic condiment is good for her.
She said: "I know it sounds disgusting but I have a little bit of apple cider vinegar in the mornings.
"It’s meant to be really good for helping you flush out toxins.
"It’s only a tiny bit and I have it with green tea and honey. My flatmates think I’m disgusting but I like it."
Despite her enviable physique, the blonde beauty insists she doesn’t restrict her diet or deprive herself of anything she likes.
She told new! magazine: "I don’t have any barriers on what I will and won’t eat.
"I don’t believe in being like that because if I think there is something I can’t do or stop myself doing then I’m more likely to want to do it.
"I think it encourages binge eating if you stop yourself from anything. I’m pretty open to having whatever."
Suki isn’t the only star who drinks vinegar.
Selena Gomez has previously spoken of her "obsession" with pickled gherkins, and admitted she is such a big fan, she even drinks the vinegary juice at the bottom of the jar.
She said: "I am obsessed with them. That is my thing and I drink the juice from the jar too."
But it’s not just in the comfort of her own home that the ‘Come & Get It’ hitmaker pops open the condiment as she also can’t resist tucking into them at the movie theatre.
She explained: "They sell them at gas stations and movie theatres in Texas. I go to the movies and have popcorn and pickles. It’s not weird. It is a thing back home that I do."
