You don't say. Justin Bieber tested the gullibility of fans and the media on Christmas Eve when he tweeted -- to instant chaos! -- that he was "officially retiring." A few tweets later, he assured his supporters: "The media talks a lot about me. They make a up a lot of lies and want me to fail but I'm never leaving you, being a belieber is a lifestyle."
"He isn't retiring, clearly," a source close to the "Boyfriend" singer, 19, reiterates to Us Weekly.
"It was a joke and he explained in two tweets afterwards!" Continues the insider, "He is basically poking fun of how quickly news spreads without anyone vetting if it is true or not."
The prank was also a great marketing ploy: "Believe," Bieber's second documentary film, hit theaters on Christmas day.
