Members of One Direction all admit to being slightly insecure, and wish they had certain traits belonging to their bandmates.
Admitting he wishes he had his friend’s toned stomach, Zayn told US radio station Hot 99.7: "I'm a little bit jealous of Liam's six-pack."
Liam admitted he wished he "was as funny as Louis [Tomlinson]," while Harry Styles said: "I wish I had Niall [Horan]'s Irish accent."
Liam has also recently moved in with his girlfriend, Danielle Peazer, because she is much tidier than Harry and Louis, who he previously shared a house with.
He said: "One is really sloppy and one's a little sloppier. I am actually quite clean."
Of Danielle's rules about his new house, he added: "I can't have it too messy or she'll have a go at me. We haven't been there long. My girlfriend's there alone most of the time. It's just a base really."
Zayn has also recently invested in property, buying a £2.2million home in north London.
A source said: "Zayn is trying to be smart with his money by putting it into bricks and mortar.
"He fell in love with the house. The deciding factor was the huge indoor swimming pool. He's already planning some pool parties for when the band are back in town."
