Beyonce and 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."

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!"

Beyonce has just completed on of her most famous performance for the year and now is prepping for the Super Bowl XLVII where she will be the headlining halftime performance. The anticipation of her performance may be more exciting than the Harbaugh brothers going head to head against each other head coaching the Baltimore Ravens and San Francisco 49ers... Ok maybe not, but still this is going to be awesome!
