Following Pacquiao's knockout bout with Juan Manuel Marquez earlier this month, the Baby hitmaker uploaded two photoshopped snaps of the fighter on the floor of the boxing ring.
One had The Lion King character Simba standing over Pacquiao alongside the caption, "Dad wake up", while another mock-up had Michael Jackson in his famous leaning pose from the Smooth Criminal video, mirroring Pacquiao just before he hit the floor.
The snaps have outraged Filipino politicians, who have threatened to make Bieber a "persona non grata" in the country unless he apologizes for his "distasteful comments".
The statement from seven members of the Philippines Congress adds, "Mr Bieber should have known that the Hon. Pacquiao has reached his stature as such as a result of sheer hard work, determination and firm belief in God, and despite (sic) such stature best exemplifies humility and grace even in defeat."
