Everything We Know About Lady Gaga's Inauguration Performance
Lady Gaga is to sing the national anthem at the inauguration of Joe Biden and Kamala Harris on January 20.
The "Chromatica" singer has been a vocal supporter of the Democrats and campaigned for a Biden-Harris victory.
The performer—whose real name is Stefani Germanotta—will be singing "The Star-Spangled Banner" at the event, as confirmed by the Biden-Harris inaugural committee via Variety.
The swearing-in ceremony usually begins around 11:30 a.m. ET on the West Front of the Capitol Building.
Others reportedly lined up to appear at the ceremony include Andrea Hall, a firefighter who will lead the proceedings with the Pledge of Allegiance. Amanda Gorman, the first National Youth Poet Laureate, will recite a poem.
Jennifer Lopez is also set to perform but other artists have yet to be named.
An invocation and a benediction will be delivered by Fr. Leo O'Donovan and Rev. Dr. Silvester Beaman respectively—both are long-time friends of the Biden family.

Tom Hanks is set to host a primetime network special on the night of January 20. A virtual parade and events will also take place and will be live-streamed.
Gaga fans will remember her performing the national anthem at Super Bowl 50 in 2016.
Following the attack on the U.S. Capitol by Donald Trump supporters last week, the singer urged Congress to impeach the president, saying he had "incited domestic terror."
On Wednesday, Trump became the first president in history to be impeached twice, with members of his own Republican party joining Democrats to vote against him.
Trump has maintained that he will not attend the inauguration of Biden, which is set to have more National Guard troops in attendance than the swearing-in ceremonies of Trump and Barack Obama combined.
Metropolitan Police Chief Robert Contee said on Wednesday: "I think you can expect to see somewhere, upwards beyond 20,000 members of the National Guard that will be here in the footprint of the District of Columbia."
The inauguration has been designated a "national special security event" after five people, including a Capitol police officer, died in the riots unleashed by a pro-Trump mob last week.
