She's waited all her life for a moment like this! Kelly Clarkson joined the likes of Beyonce and James Taylor to sing in front of President Barack Obama and nearly one million spectators in Washington, D.C. for Obama's second inauguration on Monday Jan. 21.

Attending the festivities with fiance Brandon Blackstock , Clarkson, 30, sang "My Country 'Tis of Thee" with the United States Marine Band in advance after Obama's moving address. And, as the very first American Idol champ sang her heart out, another President -- Bill Clinton -- was photographed inadvertently "photo-bombing" Clarkson in a hilarious snapshot that hit Twitter.
