AceShowbiz - Lady GaGa brought smiles on people's faces for showing up at a Kamala Harris rally. The "Bad Romance" hitmaker took the stage at the Vice President's rally in Philadelphia, Pennsylvania.

On Monday night, November 4, the 38-year-old singer/songwriter made an appearance at the political event, which also saw Katy Perry performing. During the rally, she stepped on the stage to entertain the packed audience, who attended the event to show their support for Kamala and Tim Walz.

For her performance, GaGa, whose real name is Stefani Joanne Angelina Germanotta, belted out "God Bless America" alongside a guitarist. While showing off her skills in playing the piano, she sang, "God bless America/ Land that I love/ Stand beside her/ And guide her/ Through the night/ With the light/ From above."

After finishing the song, GaGa gave a speech. She stated, "From more than half of this country's life, women didn't have a voice. Yet, we raised children, we held our families together, we supported men as they made the decisions. But tomorrow, women will be a part of making this decision," prompting the crowd to cheer. Near the end of the rally, she treated the crowd to a performance of her 2011 song "Edge of Glory".

Aside from GaGa, rapper/singer will.i.am hit the stage at the event. He delivered his song titled "Yes She Can", which he dedicated to Kamala, for the first time following its release on November 3. He was introduced by Oprah Winfrey, who rocked a white tee featuring a black "YES SHE CAN" graphic on its front side.

will.i.am sang, "Momma, what's wrong with America?/ Why can't we get along in America?/ Something's going on in America/ People entertained by the predator/ We used to be united in America/ Now we divided in America/ We all immigrants, different characters/ But together, you know, we could break down the barriers."

"If you a woman then vote for your rights/ And don't let them take away your rights/ We could be better than we ever been/ We about to have a woman president/ Haters' gonna say that we can't/ But the word 'American' says that 'I can'/ And we say, 'yes, she can,' " he continued.
