Joe Biden's inauguration will pack some serious star power.

Next Wednesday's event that will see Biden, 78, and Kamala Harris, 56, assume the positions of U.S. president and vice president, respectively, will also feature performances from two of the biggest names in music: Lady Gaga and Jennifer Lopez.

"The #InaugurationDay ceremony lineup is here! 🥳," read a tweet from the official Biden Inaugural Committee on Thursday morning, going on to share a list of names that noted Gaga, 34, would sing the national anthem and Lopez, 51, would put on a musical performance.

The rest of the list revealed that Father Leo O'Donovan would offer an invocation, Andrea Hall would lead the Pledge of Allegiance, Amanda Gorman would perform a poetry reading and Reverend Dr. Silvester Beaman would lead a benediction.

Lopez celebrated the news on her Twitter account, sharing a photo of herself with the announcement alongside red, white and blue heart emojis and the hashtag, "#Inauguration2021."

Added Gaga in the caption of a photo that showed her wearing a shirt emblazoned with the word "JOE" inside a heart, "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! 💙"

Both Lopez and Gaga (real name: Stefani Germanotta) previously spoke up during the 2020 presidential election season, with the "In the Morning" hitmaker and her beau, Alex Rodriguez, officially endorsing Biden last October. Gaga also campaigned for Biden and encouraged people to vote.

"For me, it's [about] unifying the nation again, getting rid of this hate," Lopez said in part during a video chat with the now-president-elect and his wife, Dr. Jill Biden. "I hate thinking about my kids walking around in a world where it's okay to be racist or prejudiced because our administration says it's okay."

That same month, Gaga released what she jokingly called her "new single" in a video she shared on her Twitter account — all in the name of getting fans to the polls.

The Grammy winner was also previously open about her support for Democratic candidate Hillary Clinton in the 2016 election, and has teamed up with Biden in the past to help set up trauma centers for survivors of sexual assault.

As for Biden, the president-elect recently said he isn't concerned about taking the oath of office out in the open, in light of last week's violent riots at the U.S. Capitol building.

"I'm not afraid of taking the oath outside," he told reporters on Monday, after publicly receiving his second coronavirus vaccine at Christiana Hospital in Newark, Delaware.

"I think it's critically important that there be a real serious focus on holding those folks who engaged in sedition and threatened people's lives, defaced public property, caused great damage, that they be held accountable," he added.

Biden and Harris, 56, are scheduled to take their oaths on the west front of the Capitol on Wednesday, a Congressional committee confirmed last week — despite some officials expressing security concerns surrounding the event.
