Former President Bill Clinton is obviously a badonkadonk kind of guy. As Kelly Clarkson came to the stage to sing "My Country Tis of Thee" during yesterday's inaugural festivities, Bill was snapped sticking his head out into the aisle to get a better look at Kelly's ample boo-tay!

HERE'S THE PHOTO

And Bill's not the first Clinton to get caught checking out a singer's body part, either Hillary was recently caught gawking at the well-endowed chest of Christina Aguilera. Peep that pic here.
