Russell Crowe was left scrambling to change his Twitter password on Tuesday (02Jun13) when a prankster hacked into his account and posted a picture of a naked woman on the actor's page.

The Gladiator star's followers were shocked when the raunchy image appeared on Crowe's Twitter feed and he was bombarded with messages about the strange post.

Crowe quickly deleted the image and blamed the problem on a hacker.

In a subsequent post, he writes, "Hey, I don't know what that was. Just having a chat with Dani (estranged wife Danielle Spencer) when the phone went ballistic. Sorry, gone."
