Stone-faced Obama tangos with Argentinian stunner

President Obama discovered it takes two to tango Wednesday evening as he engaged in a bit of dance diplomacy with a stunning partner at a state dinner in ­Buenos Aires, Argentina.
The president and first lady Michelle were dining in the capital when they were pulled abruptly onto the dance floor by two accomplished performers.
A dancer in a shimmering gold dress made a beeline for the president and beckoned him into the spotlight. Obama initially demurred, but she finally coaxed him up.
Hundreds looked on as a stone-faced Obama stumbled through the steps a bit, but eventually caught on to the moves.
The first lady got in on the action, too, smiling broadly as she twisted back and forth with a dapper, dark-clad dancer.
The unexpected moment came at the end of a candlelit dinner that Argentine President Mauricio Macri hosted for the Obamas. It had been nearly 20 years since a US president last made a formal state visit to the South American nation.

Elegant, slow-moving and sensuous, the tango has its roots in Argentina’s capital, which hosts annual festivals for devotees from around the world.
