Hugh Jackman has warned his fans to stay vigilant about fakes and frauds claiming to be him on social media and offering meet-and-greets in exchange for money.

The 50-year-old actor urged people not to give anyone their financial information and pleaded with his social media followers to keep themselves "safe".

Taking to Twitter, he wrote: "Thanks so much for making me aware of people using my name and likeness to create fake social media accounts. I understand these people are asking you for money to meet me. (sic)''

The Greatest Showman star then urged his fans not to share any of their private information online, posting:  ''Please know this ... I have and will never ask anyone to pay to meet me on social media. Please do NOT give anyone you do not know your personal or financial information!

In his message, the Logan actor continued to say that social media "can be amazing" when it is "used correctly".

''Social media, when used correctly, can be amazing. I love that it allows me to share my journey from every part of the world.

"However, it can also be dangerous. Please hear me ... If someone claiming to be me is asking you for money ... It is a SCAM. Please keep yourselves and your family safe.

''Love HJ (sic)''

Jackman showed just how much fun he is when he brought an Irish dad up on stage during his recent show in Dublin.

The Hollywood A-lister also dropped into a local pub to sample what he called his first pint of Guinness on Irish soil.
