Selena Gomez & Gracie 1
Selena Gomez has been going through a lot of ups and downs lately, with her on-again, off-again relationship with Justin Bieber (does anyone know their status anymore?!) and her recent stint in rehab. But despite her recent troubles, it seems Gomez hasn't allowed anything to take away from her older sibling duties! The 21-year-old singer recently posted an adorable snapshot of her and her little sister, Gracie, on Instagram and it's clear that Gomez couldn't be happier spending time with her.

Penélope and her sister, Monica, are very close! The two even created a lingerie line together back in 2012. The sisters also have a younger brother, Eduardo, who dated Penélope's famous friend, Eva Longoria, for a couple of years. I guess that's one perk of having a celebrity sibling!
