Harry Styles lead cheers for a proposal during a concert in Singapore.

The British pop singer heeded a fan's request when he asked for help asking his girlfriend to marry during the Love on Tour's Singapore leg in Kallang on March 17.

He paused the performance and said: ‘Kenneth asked for some help. Can I get some romantic music, please?'

When the band started playing, the English singer and songwriter said: ‘After you, Kenneth,' before the fan went down on one knee.

Footage shows Harry Styles beaming on stage as the stadium cheered for the surprise proposal.

The fan, Kenneth, pulled out a box while his girlfriend apparently could not believe what was happening and received the engagement ring.

Harry Styles then burst out: 'She said yes! Kenneth and Kimmy, everybody!'

He then congratulated the couple and joked: ‘What do we do now? What am I supposed to do now? You've stolen my thunder. Congratulations.'

Harry also gave a heartfelt message to his fan Kenneth who had been reportedly dating his fiance for two years.

He said: ‘Kenneth, I don't know you at all. I've never met you before in my life.

‘Kenneth, hear me, you both seem wonderful. I wish you a life of happiness. Congratulations. Make some noise, everybody.'

Former One Direction band member Harry also helped a couple with their marriage proposal during his gig in Manila, the Philippines on March 14.

The singer also stopped a show in Melbourne, Australia to help a man propose to his girlfriend on February 25.
