Justin Bieber has pledged that he is "trying to be better" after a US gossip website published pictures of him allegedly smoking a suspicious-looking cigarette.
TMZ's photos reportedly show Biebs and some friends with the apparently home-made roll up at a hotel room party in Newport Beach, California.
According to the tabloid site, JB's pal Lil Twist was also present, though the YMCMB rapper isn't captured in the snaps.
The Beauty And A Beat singer has since seemed to comment on the ensuing blaze of publicity on Twitter, writing: "Everyday growing and learning. trying to be better. u get knocked down, u get up.
“Back on tour tomorrow. ready to see u all smile. time to do what im supposed to be doing. performing. #BELIEVEtour.”
He later specifically addressed his fans when he wrote: "I see all of u. i hear all of u. i never want to let any of you down. i love u. and..thank u. #beliebers
“Like i said...2013...new challenges. new doubters... Im ready. We are ready. see u all tomorrow and everyday after that. #BELIEVEtour"
The star also tweeted about last night's show in Utah, before signing off for with the message: "SHOWTIME"
TMZ claims that the images were taken on Wednesday (2nd January), the day after a paparazzi photographer was killed while trying to get a shot of Justin's Ferrari.
The site also reports that JB had security with him, but that there appeared to be no objections to the pictures being taken.
