Lili Reinhart is mourning the death of her grandfather

She wrote on Instagram: “A few days ago, I lost my grandpa.

“It breaks my heart that I can’t be with my family during this time, as we experience this loss.

“But I’m remembering him on my own, as a simple man from Ohio who loved his Cleveland sports teams and who fell asleep in front of the tv watching old western films. He was married to my grandma for 61 years and always called her ‘babe’, which I thought was the sweetest thing.

“I wish I could’ve seen him one last time but I’ll forever hold him in my heart. Love you, grandpa (sic)”

Alongside her post, Lili shared a black and white photo of her grandfather, which was taken when he was younger.

And following her post, Lili’s friends took to social media to pay their respects, including her ‘Riverdale’ co-stars Madelaine Petsch and Camila Mendes.

Madelaine commented "love you" with a heart emoji while Camila also added a heart emoji in her own comment.

Lili’s devastating loss comes as she has been open in the past about her battle with mental health, and shared her trials in a poetry book she wrote titled ‘Swimming Lessons’.

Speaking about the project in September, she said: "If I'm going through something - depression, anxiety, a breakup - I need to talk about it. I'll talk to my friends for hours, I'll write about it for pages and pages in my journal, I'll write countless poems about it."
