Kamala Harris' campaign for president just got a major assist from Beyoncé -- and one of the singer's biggest hits!

Kamala made her first official visit to her campaign headquarters in Wilmington, Delaware, on Monday night, as she stepped out into the limelight to Beyoncé's popular tune, "Freedom."

A Harris confidante told CNN her team received prior authorization from Bey's reps to play the song.

That's a huge deal because Beyoncé is super protective of her music and has stringent rules about giving permission to anyone to use her catalog.

But Kamala passed muster with Bey. CNN says within hours of the Harris team's request Beyoncé gave them permission to play "Freedom."

Seems like Beyoncé is fully in Kamala's corner, although she hasn't come out to endorse Harris, but it's probably just a matter of time. Beyoncé's mom, Tina Knowles, has already offered Kamala her endorsement.

Still, Kamala has yet to be anointed the Democratic presidential nominee, but she's the odds-on favorite at this point, with lots of support from donors and the leaders of her party. It looks like she already has enough delegate support to cross the finish line.

As you know, Kamala replaced President Joe Biden at the top of the ticket after Joe bowed out due to increasing pressure from their fellow Dems.

Joe is going to speak to the nation later this week about his decision to drop out of the race.
