Beyoncé is set to make her long-anticipated appearance with Vice President Kamala Harris at a rally in Houston on Friday night.

DailyMail.com confirmed that Queen Bey will join the Democratic nominee after months of speculation about when she would step onto the campaign trail.

Beyoncé was previously rumored to be the special guest on the final night of the Democratic National Convention in Chicago last August.

But the convention concluded with Harris' speech and the traditional balloon drop, with no additional pop star surprise beyond Pink's performance, disappointing Democrats.

Beyonce will appear alongside her mother Tina Knowles and Willie Nelson at the Friday affair, The Washington Post first reported.

Beyonce also signaled her support for Harris almost immediately - by allowing the vice president to use Freedom in her campaign ads and at rallies.

She also threatened to send a cease-and-desist to the Trump campaign after the same song was used in Trump's social media.

And DailyMail.com reported in August that Beyonce planned to attend a fundraiser for the Democratic nominee.

Harris' event Friday is being billed as abortion-rights focused, as the campaign called Texas 'ground zero of Trump's extreme abortion bans.'

The Democratic nominee will also appear alongside Rep. Colin Allred, who is in spitting distance of Republican Sen. Ted Cruz in Texas U.S. Senate polls.

The star didn't appear on the campaign trail in 2020 with President Joe Biden, but did show up in support of Democratic nominee Hillary Clinton in 2016 alongside her husband Jay-Z at a rally in Cleveland just days before the 2016 election.

Clinton went on to lose that race to former President Donald Trump.

The Harris campaign is rolling out a number of celebrity endorsers in the final stretch.

Eminem appeared with former President Barack Obama at a rally in Detroit on Tuesday.

Bruce Springsteen will do several appearances - including one Monday in Philadelphia - in support of the Democratic nominee.

On Saturday, Lizzo appeared with Harris in Detroit, while Usher was with her in Atlanta.

Beyond Beyonce, there are questions of whether Taylor Swift might give Harris a boost in the final days.

Four years ago, Lady Gaga performed on Election Day eve alongside Biden outside the Pittsburgh Steelers stadium, helping him build up excitement in the ultimate swing state of Pennsylvania.
