Arianny Celeste Bikini Booty, Lolo Jones Olympic Cheeks, and Sara Jean Underwood Hot Butt Highlight This Week’s Sextastic Twitpic Roundup

It's Thursday and that can only mean one thing, well, two things if you count the fact that it's also the day I spend an hour staring sheepishly into the window of the pedicure place down the street watching random women's toes be painted. But the more important thing is the Sextastic Twitpic Roundup, where we gather together the finest in the past week of hot celebrity meets ego meets cell phone cameras and find the best of the best in the world of the self-published pictures.

This week's Roundup includes some seriously hot bums on the part of Arianny Celeste, Sara Jean Underwood at E3, Olympic virgin hottie Lolo Jones, some benevolent cleavage from Jamie Lynn Spears, bikini pictures from the likes of Selena Gomez, Alicia Keys, Kylie Jenner and Kendall Jenner, Fergie, and a ton more bits of self-picked hotness. Check it all out, I dare you. Enjoy.
