Bill Clinton Photobomb Kelly Clarkson During Presidential Inauguration Song [PHOTO]

Former President Clinton and his wife were in attendance at the inauguration ceremony of President Obama and may have taken the best photobomb a politician has taken so far.

Kelly Clarkson wowed the crowed at the Presidential inauguration in Washington, D.C. Clarkson belted out "My Country, 'Tis of Thee" and later tweeted, "Wow ....I was incredibly nervous and cold ha!," Clarkson said while sending fans a picture of herself shaking the president's hand. "I just wanna officially thank President Obama for opening for me haha! Just kidding :)" The singer added, "Maybe the coolest photo I've ever been in," Not knowing that a picture with another president may be the funniest and most popular one that she'll ever have.

The photobomb was posted on Twitter by Doug Gordon, a Brooklyn documentary TV producer. Following the former American Idol singer, Beyonce did the honors again, performing the national anthem. The international star performed for the President and first lady at the inauguration ball singing, Etta James' "At Last."

The two girls teamed up for a photo and Clarkson tweeted in amazement, "Me and B just hangin' out ....don't worry about it. Seriously, God did good. She is so beautiful!"
