Today's Babe of the Day is an adult film actress known as Maddy O'Reilly. If you don't know of her yet, then you'll probably want to do some research. Ya know -- for science.

Miss O'Reilly is seriously one of the hottest girls on the planet. The 24-year-old adult film star played Dorothy Gale in 'Not The Wizard of Oz XXX,' the pornographic parody of 'The Wizard of Oz.' Her seductive looks and sexy body are a dangerous combination and helped her become nominated for plenty of awards and even helped her win an AVN Award for the "Best Solo Sex Scene." She's beautiful and talented.
