There's a plethora of smoke-show models who love broadcasting their day-to-day sexiness on Twitter. Diora Baird. Adrianne Curry. Jessica Burciaga. Rosie Jones. Coco Austin. This weekend we were pleasantly surprised when we recently stumbled upon the Twitter feed of reality TV starlet and former Vegas show girl Aubrey O'Day. After a though analysis of her 1,100-plus Twitpic photos, we've concluded that the former Alpha Chi Omega sorority girl at UC-Irving and Semester at Sea alumna loves to tease and titillate her followers with voyeuristic snapshots of her T and A. This makes complete sense, especially considering O'Day once confessed to Maxim, "I’m fully groomed down there — clean-shaven. But I have a new appreciation of the ’70s girls — bushy and free." We put together a greatest hits compilation of O'Day's 20 sexiest Twitpics. Twenty reasons you'll want to start following @AubreyODay after the jump.
