Rihanna Bikini Butt, Jenner Sisters Posing, and Selena Gomez Cakes Headline This Week’s Sextastic Twitpic Roundup

With news this week that Carly Rae Jepsen has nekkid private photos out in the digisphere, we're now pretty much convinced that every celebrity under 30 has some kind of racy photos of their own making somewhere. And while the lovely ladies aren't self-publishing their fully nekkid secret pics, they are still going half the distance, providing the ogling public a sweet and hot glimpse into their private lives by way of Twitter and other social media.

This week's Sextastic Twitpic Roundup includes the ever-showoff (with the deserving body to do so) Rihanna flashing bikini chops, Kendall Jenner and Kylie Jenner for whom the world will never provide enough attention, Jo-Jo Levesque flashing her sweet cleave, Hayden Panettiere bikini posing, and much much more. Enjoy.
