Virgin Media star Simon Delaney has been targeted by fraudsters who create fake Instagram accounts.
A fraudulent profile of the TV presenter with username "Simon_Delenay" had made 24 posts posing as Simon.
He warned his followers not to engage with the fake profile.

He said on Instagram: "This is not me. Please do not accept follow or message requests.
"If you can, please report to @Instagram and then block."
Thankfully, the fake account has since been deleted.
Last year Simon found a way of connecting with his followers outside of Instagram by joining Cameo, a popular app where users can pay for personalised messages from famous faces.
Celebrities, internet personalities and familiar faces from all around the world can be found on the app charging anything from €2 to €2,000 for a message.
People often pay to have celebrities record birthday messages and messages of good luck or congratulations which they can then share with their friends and family.
The Irish actor and presenter announced his arrival onto the platform in November when he tweeted: "If you fancy a personalized message from me, or for someone who has a special occasion coming up, check out my Cameo profile."
