Gaga's 17 million followers were surprised to see a message posted online on Monday morning directing the singer's fans, or "little monsters," to a website with the promise of free Apple products.

The tweet read: "Monsters, I'm giving away FREE iPad2's to each one of you in the spirit of the holidays :)".

Another two similar messages were uploaded to the site within minutes of one another, but they were soon spotted by Gaga's representatives, who promptly removed the text.

Gaga has since changed her login details to prevent further unauthorized posts and has assured fans everything is back to normal.

Taking to Twitter on Monday afternoon, she wrote, "Phew. The hacking is over! And just in time, I'm on my way to Japan! So excited to spend Xmastime with my TokyoMonsters!"
