Obviously she isn't the "Sexiest Woman in the World" but I've seen worse choices.
People does a bigger one, their choice for 2014 was Lupita Nyong'o. The transexual looking chick from "12 Years a Slave", I think there was a thread on it.
Before that it was Gwyneth Paltrow, Beyonce Knowles, J-Lo, Julia Roberts, Christina Applegate, Kate Hudson, and Drew Barrymore going back to '07. The main takeaway from that list is that the magazine is trying to sell it older women. Julia Roberts wouldn't be the hottest women in a randomly selected Starbucks, but they're trying to say she was the hottest in the world. It's crazy.
These women would be better candidates for a "Women Braving the Wall" article.
Out of all of these women I do think Penelope Cruz is the best choice. I've only seen her in "Vicky Cristina Barcelona" but she definitely has this raw sexual appeal which I think is common in Latina/Mediterranean girls, at least for me. I also like that she took a shit on Israel a few months during that shit with Palestine.
Also I wouldn't blame the writer Tuth, he was assigned the job. It's probably one of the more desirable pieces to write too, guaranteed hits. Hell the guy wrote more about bullfighting than he wrote about her.
