The ITV2 reality show opened its latest episode with a tribute, after it was confirmed she had died at the age of 32.
Before viewers saw the latest action from the villa, a picture of Sophie was displayed along with the message: “In loving memory of Sophie Gradon.”
Bosses had previously released a statement saying: “The whole ITV2 and Love Island team are profoundly saddened to hear the news about Sophie, and our deepest sympathies and thoughts go to her family and friends.”
Presenter Caroline Flack also shared her own tribute to the series two contestant.
She tweeted: “So very sad . Such a beautiful soul .... such a beautiful smile ...thoughts and love with friends and family.”
Narrator Iain Stirling also shared one of his favourite Sophie moments during her time on ‘Love Island’ in 2016, writing: “This will forever remain on of my favourite Love Island moments. Dearest Sophie, I truly hope you are now at peace. Stay shapey x.”
Many of Sophie’s fellow Islanders, including Olivia Buckland, Cara De La Hoyde and Malin Andersson also tweeted in memory of Sophie.
Katie Salmon, who Sophie made history with by becoming the first - and so far only - same-sex couple on the show, also shared a heartfelt tribute, writing: “Your smile will be remembered forever.
“My thoughts are with your family, friends and loved ones at this horrendous time,” she continued. “Too young, too sweet. Too kind. Am sending all my love, I truly am, to everyone who had the pleasure of being in her company.”
Sophie’s cause of death is yet to be confirmed, but police have said it is not being treated as suspicious.
