After the singer quipped that he was really "Derek Bieber," the name became a Twitter trending topic, with some fans expressing amusement and others confusion.

One innocent joke from Justin Bieber is apparently enough to set off a Twitter frenzy.

On Wednesday, the singer was tracked down in Hollywood by a TMZ cameraman, who questioned him about a recent incident where Bieber reportedly refused to give his autograph to an American Airlines pilot.

Bieber basically responded that everything in the media is not to be believed. The paparazzo then asked him how it felt to be a famous person having to deal with stories written up that aren't always true.

"I'm famous? I'm a celebrity? I didn't even realize," he responded. "My name's Derek. I don't even know what you're talking about."

He went on to add: "I'm just a look-alike. I don't know why you guys are following me around with cameras." [Watch the video below.]

Both the Beliebers and non-fans immediately started tweeting about "Derek Bieber," making the joke a top trending topic on the social networking site. Many people rushed to create Twitter accounts with some variation of the name.

Yet others were just confused about who this "Derek Bieber" person was and why he was trending.
