Clad in a glittering red get-up, South Korean rapper Psy shook hands with US President Barack Obama at the 31st annual "Christmas in Washington" charity concert.
This comes just days after revelations that performances during his 2004 tour promoted killing US soldiers "slowly and painfully".
The gala benefit raises much-need funds for the US' Children's National Medical Center. Obama and his family were joined by TV personality Conan O'Brien, singer Demi Lovato and American Idol winner Scotty McCreery.
Psy galloped around on stage, performing his worldwide smash 'Gangnam Style' as the president watched. Obama gave a speech afterwards, thanking host Conan and "all the other talented folks on this stage".
Psy has since apologised for his anti-US protest songs that he performed between 2002 and 2004. In a statement to press, Psy regretted his use of "inflammatory and inappropriate language".
Will Psy's anti-American roots dampen his popularity in the West? Or is the public as happy as Obama to shake hands and move on?
