Justin Bieber Crashes Manny Pacquiao - Floyd Mayweather Presscon

Canadian pop star Justin Bieber showed up at the press conference of Floyd Mayweather Jr. and Manny Pacquiao in Los Angeles on Wednesday.

Bieber, a long-time fan of Mayweather, suddenly appeared on stage as Mayweather, Pacquiao and their respective teams were posing for photos.

Wearing sunglasses, Bieber gamely posed with Mayweather. But the pop star ignored Pacquiao, who looked surprised at his presence.

In 2012, Bieber made headlines as he posted memes making fun of Pacquiao’s downfall at the hands of Juan Manuel Marquez.

Last year, Bieber gamely posed for a picture with Pacquiao when they accidentally met in Los Angeles.
