British singer-songwriter Ed Sheeran has given his opinion on the One Direction members' physiques and joked that they're all quite slender so could probably benefit from eating a little more junk food. 

During a new interview with Ryan Seacrest, he was asked who the thought the 'buffest' member of the boyband was and said: "I don’t know, any of them... Do they bench press?”

When Seacrest admitted that member Liam Payne had previously confessed to sometimes survivng on just “coffee and Kit Kats", he added: "I think they’d enjoy themselves more if they didn’t just eat Kit Kats and drink coffee. Who wants to do that? Eat a burger now and then, man, c’mon! I’m on my fried diet at the moment. If it’s fried I’ll eat it.”

Sheeran, meanwhile, also told Seacrest that he has written around 120 songs for his forthcoming new album: "I wrote a lot of stuff. I wrote the whole of this next record. Over the course of the year, I wrote 120 songs...America is one of those countries where you have a lot of experiences and meet a lot of new people - it’s not like rapping about road changes, but there are songs inspired by Nashville and things like that, and I took more influence from music here, I got to work with a lot of very cool people over here producer-wise."
