Australian singer Delta Goodrem has fallen victim to Internet pranksters who hacked her account and sent messages to thousands of fans.

The Born to Try hitmaker discovered her account had been illegally accessed on Monday (10Dec12) and sent out a warning, urging her followers to delete any messages they might have received from imposters.

In a post on her page, she writes, "If you got a direct message from me starting with Fyi it's Spam please press report spam and delete it! Sorry guys."
