Nicknamed Frick and Frack, Backstreet Boys Brian and Nick, have definitely found a way to harmonize, but not just with their smooth voices...

Despite a 5 year age difference, the singers are the best friends. "We're always hanging out together. It's hard to say exactly why we got on so well...our personalities ties seem to have clicked," says Nick.

Well, judging from the mania that the Backstreet Boys have created in the US, it's plain to see why Brian and Nick are so in tune. Nick accredits Brian to having been the biggest influence in his life, and Brian couldn't been more pleased. "Nick is like the kid brother I never had!" says Brian. "I'm proud oh him, he's my little frack!"

Brian is learning how to cope with super stardom and according to his best buddy, he's taking it in strides. "He's totally stayed the same. I think we're all coping well, to be honest," says Nick. There is one small thing that throws Brian just slightly off balance and that's jewelery. Completely passionate about his chain (a huge hunk of gold which spells out B-Rok custom made in Australia) Brian won't let it out of his sight.

When it comes to love, the two also share similar qualities. Brian is caring, understanding, and with an outstanding talent for writing heartfelt love songs, he has no problem with displaying emotion. Nick things of himself as an ordinary, down to Earth kind of guy. Who is he kidding!? He's only part of the hottest band in the world. But still, the boys have remained grounded and enjoy the simple things in life. Brian's idea of a good night is having a special dinner with a special lady and cuddling up with good movie. Nick's ideal night would include hordes of food, computer games and hanging out with his brother or sisters. Whether it's stroking a melody, hanging out watching movies or goofing on each other, Nick and Brian are always in perfect sync.
