Barack Obama has never made a mystery of the fact that he likes to dance. We all remember that time he danced live on air with Ellen, right?

Now, the President of the United States is at it again and this time, he's gone and had a go at the tango. Obviously.

Yep, whilst attending a state dinner in Argentina, the prez decided to get up and tango with a professional dancer. As it turns out, he's really got some moves.

Not one to watch on in a jealous rage, First Lady Michelle also hit the dancefloor with a male counterpart. Talk about knowing how to work a room. 

It's been a month of firsts for Barack - earlier on he became the first US president to visit SXSW festival.
