Psy has admitted he will always be expected to perform his massive hit Gangnam Style.
The South Korean music star was one of the acts at the Capital FM Summertime Ball at Wembley Stadium, where the 80,000-sell out crowd joined in the famous Gangnam dance.
Psy said he didn't think the demand to see him perform his number one track would go away.
"It's my lifetime biggest hit ever and I think it's going to be forever. Until the day I retire I've got to do that horsey thing," he explained.
"But I've got to move on so I'm working on the new album right now so I've got to have a lot of songs several years later from now. But still at that time Gangnam Style is going to be the strongest song I think."
Psy, whose full name is Park Jae-sang, spoke of his delight at performing at Wembley Stadium
"This is a landmark place not just for the UK but worldwide," he said. "All the artists who are performing, it's like a dream to make a performance at the stadium, especially on this big occasion."
But he added that wearing just a waist coat and trousers was a mistake on the chilly evening.
"How come it's so cold in here in summer? They are saying it's the Summertime Ball, so I dressed like summer but it's really cold. It seems I'm the only one," he added.
