Fans of the Celebrity Apprentice boss were left puzzled on Thursday (21Feb13) when the businessman appeared to quote rap track Scream & Shout.
A post on his social networking page read, "These h**s think they classy, well that's the class I'm skippin", but the tweet was promptly deleted as soon as Trump spotted the mystery message.
He alerted his two million followers to the Twitter intrusion, writing, "My Twitter has been seriously hacked - and we are looking for the perpetrators."
Trump then warned Twitter bosses they needed to step up their security software to prevent losing users, adding, "Twitter will soon be irrelevant if lowlifes are so easily able to hack into accounts."
However, the online attack didn't stop the real estate tycoon from returning to the micro-blogging site - he was back to tweeting on Friday (22Feb13).
Trump isn't the only star to take action against online hackers - Australian supermodel Miranda Kerr is also working with an Internet crime unit to track down the fraudster who recently logged into her Twitter page.
