Psy, real name Park Jae-sang, paused for photographers waiting at the station.
He made a few comments saying that it was “really exciting” being in the UK and was humbled by the large greeting.
He said it was “really exciting” to be in the UK and “a great feeling” to be greeted by so many people.
However Psy didn’t spend long in London heading straight off to Oxford where he is due to give a speech at the reputable university.
Psy said, “I’m going to Oxford today, it’s really exciting, I’m looking forward to it.”
Psy will be the first Korean artist to have been invited to speak at Oxford University.
A spokesman from Oxford Union said, “He was invited by the Union’s first South Korean and east Asian president, John Seung-yoon Lee.
“The president and Psy are both from Gangnam – the area where the eponymous hit song takes its name.”
Here are a few snaps taken of Psy earlier today from Oxford University.
