Celebrate National Siblings Day With Pics of These Hot Celeb Relatives!

They've always got each other's backs

It's National Siblings Day!

Go show your brother or sister some appreciation today! Sure, they may get on your nerves at times, but at the end of the day it's all love, right?

And there's no better way to celebrate than with some of the sexiest celebrity siblings in Hollywood, like Jessica Simpson and Ashlee Simpson or Beyoncé and Solange Knowles! Yes, they're all rich and famous and share a ridiculously amazing gene pool, but they're also always around to support each other no matter what. Liam Hemsworth and Chris Hemsworth, we're talking about you!

And in the spirit of the holiday, let's have fun and enjoy a little innocent sibling rivalry!
