The two Mullingar natives have struck up an unlikely friendship over the past year after Niall (19) moved over to London as his career went stellar.
And singer Niall has defended the youngster after he was forced to apologise for being photographed smoking outside a London pub.
The star, who's an idol for thousands of young fans, described it as a "drunken mistake" and said he didn't know how he thought it was cool.
Rushing to fight his pal's corner, Bressie said: "When I was 18, I was doing things like that and ten times worse but it wasn't being magnified and to say, 'Oh it's fair enough' because he would be a role model to so many people.
"But that doesn't mean he's not still 18 years of age and he can't do things like that. I think the press should lay off those kinds of things, that's a little unfair.
"I know it's part of celebrity and being part of one of the biggest bands in the world. But there are things that I find very off-putting and unfair."
The well-known musician also explained how Niall is just one of the lads, despite all his fame and fortune. Bressie even helped the One Direction star to move into his new pad in London two months ago as he helped him settle in to the city.
"London is a city where you can be as successful as he is and it's still a very lonely place. So it's good to have people from where you're from and don't really care who he is, in the nicest possible way," he said.
