The stylish looking rainmac from Topman has white strings, a white zip and a green lining in the hood.
Pop star Harry's jacket was probably picked by a stylist when shooting the new artwork for the X Factor boy band’s latest single, while Nick probably picked his up himself.
After winning three BBC Radio One Teen Awards last week for Best Single, Best Album and Best Music Act, Harry tweeted: ‘Thank you again to @BBCR1 for having us... Thank you everyone who voted! So happy to win!! #TeenAwards good job @grimmers :D’
Nick is known for hanging out with his showbiz buddies such as Lily Allen, Kate Moss and Caroline Flack.
Speaking a few weeks ago to Heat magazine about his friendship with the One Direction singer, Nick noted that he doesn’t feel protective over the youngster.
He said: ‘I don't feel protective - he's smart and savvy enough not to need a protector… He's probably wiser and more clued up about things than me.’
‘He's conquered America and all that, and I'm like, “Let me tell you about the time I DJ’ed in Milton Keynes”... He's like, “I've just played Madison Square Garden, so I'm fine for advice, thanks”.’
