Video: Obama beatboxes for Vietnam's "queen of hip-hop"

Mr Obama immediately invited her to show off her talent, asking “do you need a few beats?”

The woman, named Suboi and renowned as Vietnam’s “queen of hip hop,” then serenaded Obama with Vietnamese lyrics about whether people are really happy if they have lots of money.

Seemingly delighted with the exchange, Obama praised the journey of hip-hop “which started out as an expression of poor African Americans” and became a “global phenomenon”.
