To Trump, she wrote: "@realDonaldTrump please concede. I know you can see how America has suffered during this election and fought over the presidency for 4 years. Please do your part in a peaceful transition of power so our transition can be peaceful too."
Earlier in the week, the 34-year-old pop superstar showed her support for Biden by appearing at his drive-in rally in Pittsburgh. Decked in a blue jumpsuit and a blinged-out "Vote" mask, Gaga took the stage to give an impassioned speech, explaining that she doesn't "need to tell you why" to vote for Biden, because "like me, you’ve experienced the last four years and have all the evidence you need to look at this choice and know in your heart, without any doubt, that Joe Biden is the right choice."
During the rally, the singer also performed her hits "Yoü and I" and "Shallow."
