Lady Gaga will sing the national anthem at Joe Biden's inauguration and Jennifer Lopez will give a musical performance on the West Front of the US Capitol when Biden is sworn in as the nation's 46th president next Wednesday.
The announcement of their participation comes one day after word that Tom Hanks will host a 90-minute primetime TV special celebrating Biden's inauguration. Other performers include Justin Timberlake, Jon Bon Jovi, Demi Lovato and Ant Clemons.
The singer wrote on Twitter that she was honoured to be performing.
She wrote: "I am deeply honored to be joining @BidenInaugural on January 20 to sing the National Anthem and celebrate the historic inauguration of @JoeBiden and @KamalaHarris!"
