Manny Pacquiao singing 'Let It Go' from Disney's movie 'Frozen'

Because Manny "Pacman" Pacquiao loves to sing whenever he is away from the boxing ring, he belts out the Frozen theme song Let It Go.

After negotiating with Floyd Mayweather Jr. over a possible $300 million grand fight, Pacman spent his free time by singing the theme song of 2013 Disney film Frozen.

This only shows that Pacquiao enjoys singing like any other Filipinos out there.

Manny had his singing career before in which he released two music albums.

After a very long wait and countless discussions between the two camps, Pacquiao is now confident of having a fight with unbeaten Mayweather.

There had been some serious negotiations for the possibility of their fight, and it would probably be geared up for the next year.

But before that, the Filipino boxing icon is set to fight Chris Algieri this coming November.
