MANILA, Philippines (The Adobo Chronicles) – It is common knowledge that Canadian singer Justin Bieber is a solid Floyd Mayweather fan, always standing beside the boxer during the latter’s boxing fights, including Saturday’s bout with Manny Pacquiao.

But a TMZ video showing Bieber uttering the four-letter curse word when someone in the crowd screamed Pacquiao’s name might have been the final straw for the Filipinos.

The incident happened just hours before Saturday’s fight, as Bieber partied with a group of fans and supporters at his hotel in Las Vegas.

The Adobo Chronicles learned that Bieber has been permanently banned from visiting the Philippines, let alone holding a concert in Manila as part of the singer’s planned tour of Asian countries.

The Philippine ambassadors and consuls in the U.S. and Canada received a diplomatic memorandum from the Philippines’ Department of Foreign Affairs advising them to deny Bieber a tourist or any other non-immigrant visa to Pacquiao’s motherland.

Now Bieber knows that he can f*** Pacquiao but he cannot mess with the Filipinos.
