Justin Bieber just can't catch a break.  He's been forced to apologize for allegedly disrespecting the flag of Argentina while onstage Saturday night.

During Justin's concert in Buenos Aires, fans threw two Argentine flags onstage, but as video shows, Justin swept them off the stage using his shoes and a microphone stand.  After outraged fans attacked the singer on Twitter, Justin wrote, "Heard about what is going on with me down in Argentina and im shocked. I love Argentina and have had some of the best shows of my tour there. People throw stuff on my stage all show and i get it to the stage hands to get off so no one got hurt."

He continued, "that video i saw a bra and thought it was a shirt. Im being told by my team it was a shirt but even if it was a flag I would never do anything to disrespect Argentina or the people of Argentina or the fans. Im so sorry for anyone who took my actions the wrong way and I hope you can forgive this mistake."

"So once again to the people of Argentina. Im sorry if that was taken the wrong way and im sorry for my mistake. I hope u can accept this, And I loved my time there performing for you and look forward to coming back. I gave my all and I know the fans did there too. te amo."

Justin concluded, "I would never do anything to disrespect my fans. I dont like having to defend myself but this time it was needed as I mean no disrespect…and to all the beliebers ALL AROUND THE WORLD. I love you and thank you for always standing by me. Much Love to Everyone. thanks."
