Your favorite stars could be uniting for a massive inauguration-day concert — only, not for the actual inauguration.

California resident Trish Gilbert started a petition on December 16 to ask prominent celebrities to stage an anti-Trump concert on January 20.

Gilbert wants the proposed "Freedom & Unity Concert" broadcast on TV and streamed online that night, in direct conflict with Trump's inauguration festivities. Suggested performers include Beyoncé and Jay Z, Madonna, Katy Perry, Bruce Springsteen, Jon Bon Jovi, Justin Timberlake, The Dixie Chicks, Neil Young, Lady Gaga, and even the cast of "Hamilton." 

Concert proceeds would go to the American Civil Liberties Union, Planned Parenthood, and other charitable causes.

The petition garnered more than 60,000 signatures in a week.

Through a combination of Facebook and Twitter shares, the petition sits just 15,000 signatures shy of its 75,000-signature goal.

"The thought of this concert makes me so happy. It has turned my frown upside down. Let it happen!" wrote one supporter.

Former secretary of labor Robert Reich endorsed the idea on Facebook on December 18. A few days later, Politico reported that other players are working to pull together a similar event. Mark Ross, the son of former Time Warner CEO Steve Ross, is rumored to be organizing a star-studded inauguration day concert.

"The talent is banging on our doors to do this," a source told Politico.

Trump, meanwhile, is struggling to pull together an inauguration event of his own.

A number of celebrities, including John Legend, Adam Lambert, and Elton John, have all pledged not to perform at his inauguration. Others who campaigned for Clinton, like Beyoncé, Alicia Keys, and Katy Perry, are unlikely to do it either.

Sources told TheWrap that bookers are being offered ambassadorships in the Trump administration if they can pull in talent for inauguration day. So far they have roped in a 16-year-old "America’s Got Talent" contestant, the Mormon Tabernacle Choir, and the Radio City Rockettes. (Many Rockettes are reportedly very unhappy with this development). 

Trump has denied that he's trying to book celebrities for his inauguration, tweeting, "The so-called ‘A’ list celebrities are all wanting tixs to the inauguration, but look what they did for Hillary, NOTHING. I want the PEOPLE!"

It's unclear why he's tweeting about the inauguration instead of, say, getting national security briefings.
