Justin Bieber has apologised to his fans after he was caught on camera 'flipping off' photographers.
The teenager and his girlfriend Selena Gomez were confronted with a paparazzi gang as they left a restaurant, where they had been celebrating the singer's 17th birthday, in Los Angeles on Tuesday night (01Mar11).
And the upset Baby star let his displeasure be known by raising his middle finger to the photographers, who gleefully snapped away, as he drove off.
The pictures have since circulated online around the world, prompting an embarrassed Bieber to issue an apology to fans and parents who may have been offended by what he did.
He insists he'll "try to do right" in the future and not "react in anger".
In a series of birthday posts on his Twitter.com page, he writes, "Had a great bday and at the end of the night we got surrounded by paps and I reacted in a way I know better. I'm sorry. It's not always easy but I know better than to react in anger.
"Life has it's ups and downs but u guys r always there 4 me. I will make my mistakes but I promise 2 continue 2 grow with u and try 2 do rt (right)."
