‘Voice’ contestants talk working with Mary J. Blige

>> back now at 8:42 with an exclusive preview of the battle rounds that begin tonight on the nbc hit show "the voice," brian mcloughlin and add am keith from team adam levine . guys, good morning.

>> hello.

>> we didn't even bring out the fog machine for pete townsend . that's how big you are. we've got fog for you. is this strange for the two of you because in the battle round format they have turned teammates against each other, brother against brother? is it odd to be competing against a guy who has been your teammate?

>> had a great time with it. friends going into it and we saw it. such different singers. we'll do our own thing and they will like one more than the other. not me against him. trying to do the best i could, and we're so different. brian, has to be a little bit of tension. at the end you want to win "the voice" and you have to eliminate him to do that.

>> both well prepared and trained really well going into it. it is weird because we've become really good friends, but we're just -- we're both hungry for it, you know, so it's just -- it's down -- it's up to the coaches really, you know.

>> an interesting twist to the format this time around. whoever is eliminated tonight may not just quite be done because one of the other teams could pick you up, whether it's christina or seal oerk cee lo , anywhere you'd like to go if god forbid you're eliminated?

>> if i'm eliminatedo[ happy if anyone wants to steal me, a tough decision depending on who it is. hopefully that wins.

>> is there a strategy tonight when you go head to head? differently than singing onok your own up there?

>> just do your thing, and enjoy it. like i just -- we couldn't help but keep laughing with each other, even when it came down to the performance. just having a good time the whole way through, and that's what we both want to do, just giving it our all.

>> you have mary j blige helping you. is that intimidating walking into a studio with not only adam but mary j blige ?

>> unbelievable. one of the biggest stars in music. we're in there now working on a song and giving me advice. it was unbelievable, and it was intimidating at first but at end of the day it was constructive, and they were trying to help us and sort of make us the best that we can
