In the photo shared with fans, Gaga poses inside of the Capitol building wearing an all-white, sweeping, custom cape dress courtesy of Givenchy by Matthew Williams, which she paired with a matching face mask. She styled her platinum locks in a braided updo.

In her caption, the star alluded to the traumatic riots that took place at Capitol Hill last week as she wished for love and non-violence.

"I pray tomorrow will be a day of peace for all Americans. A day for love, not hatred. A day for acceptance not fear," wrote Gaga. "A day for dreaming of our future joy as a country. A dream that is non-violent, a dream that provides safety for our souls. Love, from the Capitol ??"

Gaga was also photographed outside of the Capitol building, as she greeted National Guard soldiers.

Gaga isn't the only superstar set to take the Inauguration Day stage tomorrow. Fellow musicians Jennifer Lopez, Justin Timberlake, and Demi Lovato are all also scheduled performers for the day's celebrations.

Gaga was a vocal supporter for the Biden-Harris ticket leading up to last November's presidential election. Along with encouraging her fans and followers to get out the vote with a series of encouraging social media posts, she also performed at a fundraising benefit in Philadelphia for the now President-Elect.
