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.
The pop goddess may have been the star musical attraction, but she had plenty of company from Hollywood at the Capitol.
Katy Perry and John Mayer sat side-by-side, with Perry in an orange-striped coat and wide hat.
Actress Eva Longoria was seated on the platform outside the Capitol after making an appearance at a Kennedy Center performance on Sunday night.
