Weekly Sextastic Twitpic Roundup Features Aly Michalka and Kim Kardashian and Much More…

After doing a bunch of these weekly Twitpic roundups now, we're starting to get a feel for who the sextastic celebrities are who just can't get enough of being photographed, so they take photos of themselves. Kim Kardashian is obvious. If a camera doesn't film her for more than an hour she starts to get nervous and starts posing for her own cell phone cam in the mirror. Her half-sisters Kylie Jenner and Kendall Jennernow in that same category. Coco, natch. Adrianne Curry, double natch. But also some unexpected surprises.

Check out this week's sextastic twitpic roundup and see who's pimping their own bad-selves on camera.
