The reality TV star took social media earlier this afternoon to share the sad news with her followers, just hours on from enjoying a night out with her former villa housemates Antigoni Buxton, 26, and Paige Thorne, 24.
Danica, who enjoyed a brief stint on the ITV2 show earlier this year, shared a snap of herself alongside her late loved one posing together in a field as she broke the news on her Instagram Stories today.
Captioning the tribute image, Dancia, 21, wrote: "I am in utter shock, rest in peace you beautiful boy, a friendship I'll treasure forever RIP."
Danica's seemingly received the devastating news after enjoying a night on the tiles with Love Island pals Antigoni and a newly-single Paige.
Before sharing her touching tribute online, the reality TV star's Instagram Stories were filled with snaps and clips from the trio's boozy evening in London together.
As she dined at Mayfair's luxurious Chinese restaurant, Park Chinois, Danica looked sensational in a sparkly outfit from Primark, consisting of a mini-skirt and a skimpy crop top.
Danica's night out with her two villa housemates comes following Paige's split from two-time Love Island star Adam Collard.
Before the former couple confirmed they had called time on their romance, Danica admitted she wasn't sure if the pair had split but had reached out to her pal Paige.
Speaking on the red carpet of the National Television Awards last month, Danica told the Mirror: "I saw all the articles that apparently some of the Islanders have spoke out about it [Paige and Adam's split]. I need to have another conversation with Paige and see if she's OK.
"I've got no idea really if they are together, I don't know. But I hope she's OK, that's my concern.
"I've seen little bits and I know being in the public eye it isn't nice for either of them I just hope they're doing the right thing for them."
She added: "Are they together? I'm not sure, it's gonna have to be a little girls' chat I think!"
It seems a little girls' chat did happen, in addition to a girls' night out on Tuesday.
"My baby girls," Antigoni gushed on Instagram last night as she shared a snap of herself, Paige and Danica all decked out in Primark gear.
Danica is also single these days, despite leaving the Spanish villa with footballer Jamie Allen, 27, over the summer.
The dancer and footballer's romance was clear to have ended after Danica was pictured kissing The Only Way Is Essex star Roman Hackett outside a train station just weeks on from returning home to England.
Speaking to the Mirror on the red carpet for the People's Pet Awards in September, Danica explained: "Me and Jamie were never together. We came out the villa and we very much liked each other and things were going well, but it sort of started to fizzle out – he has his life, I have mine.
"It's not quite worked out as we planned but it doesn't mean that there wouldn't necessarily be anything in the future it just means that right now we're just doing our own thing.
"I've got nothing but good words to say about him and, who knows really. What will be will be."
