WASHINGTON (AP) – Kelly Clarkson says it’s the coolest photo she’s ever been in: a photo of her shaking hands with President Barack Obama after she sang at his inauguration. It’s the picture of Clarkson with another president that’s taken fire on the Internet: Bill Clinton. He photobombed her as she sang “My Country ‘Tis Of Thee.” The photo shows Clinton peeking around the person in front of him so he could see Clarkson.
