Beyonce drew a loud cheer at President Barack Obama's second inauguration even before her impressive rendition of the national anthem.
The applause started when she took her place with Jay-Z at the Capitol to watch Obama take the oath before hundreds of thousands of people.
James Taylor kicked off the musical performances, strumming his guitar and singing America the Beautiful.
Kelly Clarkson followed with an unusual arrangement of My Country 'Tis of Thee.
Then Beyonce was introduced, and the crowd again roared its approval.
