since u been pontiff

I heard that Kelly Clarkson was performing before the Pope conducted that massive Mass at Yankee Stadium. In fact during public radio's coverage of it you could hear "Since U Been Gone" in the background. Weird.

She also helped kickoff the 2008 Salvation Army Christmas Kettle drive at the Dallas Cowboys' Thanksgiving halftime. So maybe she just digs that whole church and charity scene.

Still, "Warm-Up act for the Pope" -- it's hard to top that without being Pope yourself.
