Ed Sheeran claims Harry Styles is very well-endowed.

The 'Sing' hitmaker insists the One Direction star didn't inspire him to write the track 'Little Things' for the group because his close friend has a very big penis.

The 24-year-old singer said: ''He [Harry] definitely hasn't got a little thing, so no, I did not write 'Little Things' about [his] little things.''

Ed also claims Harry, 21, even leaked a naked picture of himself because he is proud of the size of his manhood.

Speaking to New Zealand's ZM Online, he added: ''Did you know Harry leaked that picture himself? He leaked his own picture....I think it's amazing. He was just like 'no one knows.' ''

Meanwhile, Ed admits he has no plans to start dating again after recently splitting from his long-term girlfriend Athina Andrelos.

He said: ''I am single, but I'm not really up for not being single. I've gone through my whole life from one relationship to the other, and I kind of have relied on that for happiness. I don't want to sound like a d**k, [but] I want to be able to have proper happiness and not rely on other people for that.''
