Niall Horan has complained that his Twitter account was hacked - after an unusual message appeared about him having a spotty bottom.
The One Direction singer, 19, had been telling fans about his trip to Ghana for Comic Relief shortly before the offending tweet occurred.
He told his nine million followers: "I've seen the slums right in front of me! This is no joke! They really need your help! Poverty is real. Massive thanks to @rednoseday for taking us to Ghana! It was incredible! real eye opener! We take so much for granted over here!"
But hours later, he appeared to ask fans a more personal question, writing: "Have a massive spot on my arse. Wondering should I squeeze it. What do ye think?"
The Irish singer later said: "OK I don't know what happened with that last tweet."
The message was removed from his Twitter page and Niall told a fan: "I got hacked again."
Last month, Niall's Instagram page was apparently targeted by hackers who pretended to be the star.
