Washington, DC - Lady Gaga will sing the national anthem at President-elect Joe Biden and Vice President-elect Kamala Harris' inauguration on January 20. The Chromatica star campaigned for Biden throughout 2020.

This will be the second time Lady Gaga has performed the Star-Spangled Banner at a major national event, the first being her much-praised rendition at the 2016 Super Bowl.

A Presidential Inaugural Committee official told CNN they are producing a primetime special to celebrate Biden's swearing-in instead of the traditional celebrations, due to concerns over the pandemic.

The celebrity-filled line-up for next week's festivities includes singers Demi Lovato, Jennifer Lopez, Jon Bon Jovi, Justin Timberlake, and Ant Clemmons.
