(Completed) What's it like being Justin Bieber's little sister? Is it all glamour, parties and awards? Or is it hard, busy and fun? Well, let's ask Kaitlyn Bieber. She's Justin's little sister and he would rather die than see his little sister heartbroken or in pain. Kaitlyn's been there since the beginning, but finally got her own spotlight in the modelling world. She also travels the world, has the greatest brother, an amazing best friend, a awesome mother and a FLAMAZING boyfriend! But is it really all fun and games? All work and play? Or is there some charity work, babysitting, CD signings, photoshoots, dates, beach parties and summer jobs?
