Sydney - Hollywood heartthrob Hugh Jackman has apologized to fans for getting staff to post bulletins on the social-networking internet site Twitter on his behalf, news reports said Thursday.

The new medium is supposed to be a way for people to spontaneously communicate their everyday thoughts and actions, but increasingly is being used by celebrities like Jackman to fake the personal and the intimate.

The Australian actor was exposed as a fraud when a posting referred to the Sydney Opera House as the Opera Center.

"Having lunch on the harbor across from the Opera Center. Loving life!" the Twitter message read.

It turned out that the person keying in the message was half a world away from Australia's biggest city and unaware that the way the locals spell it, it's "harbour" not "harbor" and "centre" not "center."

"Sometimes, I don't always get online and type," Jackman admitted to national broadcaster ABC. "Sometimes, I talk and someone if my office says to me 'OK what are you going to say?' and I say 'Well, I'm going down to Sydney.' I like to say where I go and stuff like that," he said.

"So I communicate that across the phone and when that got translated by someone American in my office it came out all wrong. So it was my communication but not my typing."

Jackman didn't say whether he really did have lunch on the harbour across from the Opera House. (dpa)
