The boy band - made up of Niall, Harry Styles, Liam Payne, Louis Tomlinson and Zayn Malik - always look out for each other, but especially Niall because he's the ''cute'' one of the band, and they would all take a hit for him.
Louis said: ''There is no doubt Niall is the cute one. In the nicest possible way I would much rather see any of us punched than Niall.''
Liam added: ''I feel really protective towards Niall.''
Harry admits he would go ''psycho'' if anyone ever harmed the blonde Irishman because he's such a sweet person.
He told You magazine: ''If you saw someone punch Niall you would just go psycho.''
Liam added: ''I'd kill him.''
Zayn admits that even though 19-year-old Niall isn't the youngest in the band they all have a maternal instinct towards him.
He said: ''I don't know what it is, but even though he isn't the youngest, he's the one we feel almost maternal towards.''
