Justin Bieber has hinted that he may take a break from the spotlight with a cryptic tweet.
The Boyfriend hit-maker teased that a hiatus may be on the cards as he took to the social networking site after he was booed at the Billboard Music Awards, where he accepted the Milestone gong.
"Gonna take some time," he wrote, adding: "focused. #musicjournals"
He tweeted: "I know who I am. #giveback" with a link to TV footage featuring his surprise visit to a US school, where he gave out food donations.
Justin, who won three gongs at the Billboards, alluded to the tumultuous weeks he's had in the public eye in his acceptance speech.
"I'm 19 years old; I think I'm doing a pretty good job. And basically from my heart I really just want to say it should really be about the music, it should be about the craft that I'm making. This is not a gimmick," he said.
"I'm an artist and I should be taken seriously and all this other bull should not be spoken."
