Sheridan Smith’s ex-boyfriend Graham Nation dies aged 39

'The most genuine soul'

The stylist worked with a number of high-profile clients during his life, including Demi Moore, Venus Williams, Catherine O'Hara, and Jared Leto.

According to the LA County Department of Medical Examiner, he died at a gym in LA. It's been reported that he died on Valentine's Day.

The case is pending further investigation. Graham and Sheridan Smith dated for a period in 2017.

The Mirror reports that the Gavin and Stacey actress 'really fell' for him.

Nation, who had over 100,000 followers on Instgram, was posting regular updates to his page right up until his death.

On February 13, he shared a photo of Marissa Bode, explaining that he had done her hair. Naturally the comment section is now littered with condolences for Nation.

One wrote: "The most genuine soul. RIP."

Another wrote: "Really gonna miss you, rest in peace."

A third said: "Watching you cutting hair in your living room years ago to all that you've accomplished was inspiring, rest in peace and sending love to your family. This is heartbreaking."

One more wrote: "10 years of knowing you, from cutting hair in our hometown to witnessing you take LA by storm. You were never too busy to be thoughtful. You were never too big to smile at everyone.

"You were the most incomprehensible artist. Enough talent to have the biggest ego but instead so humble and sweet. I always described you as an angel on earth. I just never thought you would leave this soon. Rest in Power, brother the world lost one of its brightest lights."

He was 39.
