Taking to Instagram stories, Amber blasted the false stories saying that her romances are ruined by untrue stories.
“Any relationships or dating that I've got going on gets ruined immediately by stories like 'this is who she is dating now'.”
“Am I? Huh? Wait, I'm heartbroken?” she joked.
“And now you've just ruined my actual s*** that I've got going on. So thank you,” she said, adding: “If you wanted to know who I was really dating you'll never find out because of this kind of shit everyday stop lying.”
It came following a story was published in the British media claiming that she was linked to Grealish who has also been recently linked to TV presenter Emily Atack.
According to The Sun, Amber told a friend that she’d like to get in touch with Emily to find out if there was any crossover, telling her pal: "We’ve met up several times and were messaging a lot. I really thought there was something between us."
Last week it was reported that the 26-year-old Manchester City player was enjoying a new friendship with 31-year-old former Inbetweeners actor Emily.
Jack is currently in a long-term relationship with childhood sweetheart Sasha Attwood.
The publication also claimed that Sasha told her boyfriend he had to choose between her and Atack.
Amber Gill has denied that she is involved with the soccer star.
The Newcastle beauty won Love Island in 2019 alongside Irish man Greg O’Shea after they hit it off on the romance reality show.
A few months later however, their romance was not to be and the couple parted ways.
During an Instagram Q&A with fans in September, Amber revealed that appearing on the show potentially ruined her dating life.
"Nobody wants to hear about my dating life, with all due respect my dating life is non-existent."
“'I'd say it's worse now than what it was before. People used to comment on us all the time - now they don't,” she said.
"I don't think it's about me. But it's good because I don't have time for that anyway. I'm busy working."
Back in January Amber teased that she was in a relationship telling Entertainment Daily: “"I'm not saying anything else. I'm not single and ready to mingle, that's all I'm saying.”
She also revealed that the mystery man is someone she knew before lockdown: "It's someone I've known from before, it's not somebody I've known from lockdown onwards. But yes I'm happy, I'm really happy," Amber said.
It was later revealed that the mystery man was Rory Colhoun, an entrepreneur who owns a dog grooming business.
However their relationship ended suddenly in February. It is believed that the end of their romance came when Amber found out that he was found guilty of a nightclub attack in Leeds that left the victim brain damaged.
It has been reported that he was tried at Leeds Crown Court for the attack in 2015 which left the victim in critical condition.
Rory pleaded not guilty in 2017, but was sentenced to three years and four months imprisonment for wounding with intent and eight months concurrent for attempting to cause GBH with intent.
