Sam Smith revealed he had asked the Beyonce for tips on how to eat more healthily before shedding about 40 pounds over the last few months.
He said: "I did have a conversation with Beyonce about food, which was great."
The 22-year-old star failed to mention whether he'd signed up to the 33-year-old beauty's vegan food delivery service but he has been put on a strict diet by celebrity nutritionist Amelia Freer and is no longer allowed to eat gluten, sugar or processed food.
Sam admitted he made the decision to revamp his diet and fitness regimen after seeing photographs of himself on holiday in Australia.
According to The Sun newspaper, he said: "I f***ing hated that. I don't want to be the perfect pop star, I'm far from that. But I saw that picture and thought, 'I hate how I look'."
Earlier this year Sam boasted about how he'd managed to shed more than 10 pounds in two weeks and "completely transform" his relationship with food thanks to Amelia and her book Eat. Nourish. Glow.
He wrote on Instagram at the time: "Three weeks ago I met a woman who has completely changed my life. Amelia Freer has helped me lose over a stone in 2 weeks and has completely transformed my relationship with food. Everyone go check out her incredible book and start to live healthy. It's not even about weight loss it's about feeling happy in yourself. Love you Amelia & thank you for making me feel so happy inside and out @ameliafreer #eatnourishglow."
