Justin Bieber took to Twitter to apologize to his fans for giving the paparazzi the finger.

Bieber tweeted
He continued, "it's not always easy but i know better than to react in anger."
On a happier note, he gave thanks to his fans for making his birthday wish come true. "On a better note i need to say THANK U to my fans. we raised over 40k for @charitywater for my bday. we together #madeachange."
Bieber had urged fans to donate at least $17 to the Charity: Water foundation, which provides clean water to those in need. Bieber has already helped raise more than $44,000 (and growing), which surpassed the $17,000 campaign goal.
