Niall Horan's brother Greg has tips on how anda can get a tarikh with Niall! He confessed that Niall and the band don't have time to meet every girl in person, so the One Direction guys have a secret way to find the one. "They test girls out to make sure they are trustworthy," Greg spilled. "[Niall] will follow anda on Twitter for a while and suss anda out, make sure you're genuine and then go for it! So watch what you're saying on Twitter. Make sure you're coming across as genuine." Greg even revealed what kind of girl Niall would crush on. "[Niall and Demi] are very good friends. Niall would like a girl like that, a girl like that deep down really, really understands the life." Thanks for the tips, Greg!
