Olivia Wilde, who can be seen this summer in both 'Cowboys & Aliens' and 'The Change-Up,' is -- we'll just say it -- quite likely the most beautiful woman in the world. These days she's awful busy, which is good for us because that just means we get to see more and more of her.

Now, as part our ongoing Summer's Sexiest Women series (see: Natalie Portman, Penelope Cruz, the lovely ladies of 'X-Men,'Blake Lively, Megan Fox and Rosie Huntington-Whiteley, Rosario Dawson, Mila Kunis), we present you with a photo gallery of Olivia at her finest, followed by a video collection of some of her sexiest work.
