The Filipino star was looking for someone to belt out the pre-fight anthem for his 17 April (14) bout with Timothy Bradley when he found himself sitting next to Ashanti at a basketball game.
She says, "I'm such a huge fan of Manny Pacquiao! I have family in the boxing business.
"When I found out we were sitting next to each other courtside at the (New York) Knicks game, I said to my dad, 'We should take a picture!' I told Manny I was a big fan and was so excited when he asked me to sing the National Anthem at his upcoming fight and I can't wait. I actually love boxing! Manny's such a champion and I can't wait to cheer him on!"
