Sophie Turner Boston Strong Butt, Nina Dobrev Upskirt, and Rihanna Covered Topless Highlight the Sextastic Twitpic Roundup

What a wonderful week of sextastic celebrity self-pics. Not so much in quantity, but in the skin reveals of some of our true favorites. But we'd like to honor a specific standout in curvaceous wooty model Sophie Turner, who not only flashed one killer bottom, but did so with the Boston Strong rallying cry in support of the bombing victims of the Boston Marathon terror attack. That's hot and classy and we salute that booty.

Joining Sophie in the circle of must-ogle this week in the Sextastic Twitpic Roundup includes Ireland Baldwin bikini show off, Rihanna covered topless and in bikinis, Candice Swanepoel bikini bottom heaven, Nina Dobrev in a perty panties upskirt, and much more. You owe it to the inevitable lousy N.Y. Jets draft selection today to view each and every one of these self-published celebrity pictures. Enjoy.
