Hottest actress?

If I just go by actresses under 40 today and only go by hotness any of these women. I'm sure I missed a lot but here's 20 off the top of my head.

Alicia Vikander, Ruby Rose, Gal Gadot, Melissa Benoist, Alexandra Daddario, Morena Baccarin, Eva Green, Margot Robbie, Evan Rachel Wood, Alison Brie, Megan Fox, Amber Heard, Elizabeth Olsen, Yvonne Strahovski, Emily Ratajkowski, Karen Gillan, Sarah Wayne Callies, Olga Kurylenko, Jessica Brown Findlay, Katharine McPhee

Charlize theron as long as she alive.

Emmy Rossum is just about perfect, IMHO

Marie Dressler. No contest!

Hottest working today , is this also based on how they look today?
(i.e. not how they looked 10 years ago or whatever)

for how they look right now:
Priyanka Chopra
Margot Robbie

but if we can choose from how they used to look-
Rachel Weisz from 17 years ago
Monica Bellucci from 17 years ago
Salma Hayek from 17 years ago

edit to add Halle Berry from 15-17 years ago

I guess 2000 was a very good time for hotness, or else I just am not that up on the new actors and actresses, because it seems like most of my hottest picks were at their peak around 2000

Aishwarya Rai
Li Bingbing
Zang Ziyi
Michelle Rodriguez

Can't believe no one has mentioned Jessica Alba yet. Granted now she's mainly a mom and entrepreneur, but she's still way hotter than most actresses 20 years her junior.

Marion Cotillard.
