Pope - a - palooza

Pope Benedict XVI, Kelly Clarkson, and 25,000 screaming fans in Yonkers, New York this past Sunday?

Now that's a show.

Donned in a demure blue dress, Kelly peformed "Ave Maria" for the Pope at St. Joseph's Seminar as he wrapped up his first visit to the U.S.

Guess Kelly thought that the lacy black tank top, ripped jeans, and silver-studded belt that she wore to belt out "Since U Been Gone" before Pope Bendict took the stage was a bit too punk -- even for P-Ben.
