Cape Town - As long as we can remember Mary-Kate and Ashley Olsen have always been the sisters ruling the fashion game.
But this year the Hadid sisters are proving that nothing is more dominating than sisters who rock the runway together.
Gigi Hadid is the tall blonde 'American' beauty while Bella is the brunette edgy one. Both have completely different styles and both can be seen on magazine covers, walking the runway and music videos.
We smell a perfect match right here...
Here are 9 reasons how these sisters are becoming our favourite sister act:
1. Anybody ask for cover models?
2. How's about two?
3. Anybody ask for hotness?
4. We did!
5. Double the trouble?
6. We thought so.
7. We love a cute piggy back moment...
8. And a stare off...
And lastly...
