Ellie Goulding is to perform in front of Barack Obama at America's National Christmas Tree lighting ceremony.
The 24-year-old British singer - who earlier this year performed at the royal wedding of Prince William and Kate Middleton - will join the Black Eyed Peas and Kermit the Frog at the ceremony near the White House.
President Barack Obama and his family will officially light the tree.
US TV presenter Carson Daly will host the ceremony and other performers will include Big Time Rush, the band OneRepublic, country star Rodney Atkins and singer Marsha Ambrosius.
This will be the 89th year for the holiday tree lighting. The tradition began with President Calvin Coolidge in 1923.
This is the first lighting of a new National Christmas Tree that was planted in March.
It's a 26-foot-tall Colorado blue spruce from a New Jersey tree nursery. Strong winds in February toppled the last tree that had stood on the Ellipse since 1978.
