Britain's Got Talent DJing drummer MckNasty says he does not expect any special treatment on the show just because he is Labrinth's older brother.
The 27-year-old got four yeses from the ITV show's judges when he DJed and drummed along to the Psy hit Gangnam Style.
MckNasty, real name Josh McKenzie, said: "The thing is we can't help who our mothers are - I didn't choose him as my brother and he didn't choose me, we're just brothers. Whether it's an advantage to me or not, I don't want it to be an advantage to me. I want to make my own way and try and do my thing.
"Obviously support from Labrinth is always a beautiful thing, in the same way that he still wants my support.
"In terms of where I am in my musical career, he's a lot bigger than me and is out there to the public. So him giving me advice like, 'Make sure you carry yourself well, make sure you speak well.' That kind of support is what I need from him and that's what I get from him."
Labrinth is signed to Britain's Got Talent head judge Simon Cowell's Syco label but MckNasty does not expect that to increase his chances in the upcoming rounds.
"Having an advantage like 'Yeah, he's my brother so I should win' - nah, it doesn't work like that, I want to be here on the merit of what I do and that's what I would want the audience and the nation to understand.
"That's what I'm about really, you don't get this by someone just putting all the food on the plate for you, I want to go out there and work for it."
He also insisted there was no rivalry in their family: "I'm his elder brother, he's my younger brother, he pushes me big time in terms of what I'm doing and he makes me feel like 'He's doing that, I need to be better.' Or I'll do something and he'll come to a show and go, 'Woah that's wicked man', and that'll push him to go and do something, so there's never any kind of rivalry, it's always very helpful.
"We just didn't grow up like that, we didn't have much. If we saw someone playing really good basketball then we'd have to step our game up. That's what it is when you come from a big family."
