Madonna continued to rally for Hillary Clinton last night, when she announced a surprise concert on Twitter in support of the Democratic presidential candidate. The pop icon performed a few of her hits during an acoustic set that took place in Manhattan's Washington Square Park.

Along with her son David Banda and hundreds of attendees, Madonna sung her classics like “Like A Prayer,” “Express Yourself" and "Rebel Heart,” as well as covers of John Lennon’s “Imagine” and folk staple “If I Had A Hammer.”

“This concert is about unifying us. How are we going to keep America great?" Madonna said on the eve of Election Day 2016. She continued,

“We are going to elect a president who does not discriminate against women, who does not discriminate against the LGBT community, who does not discriminate against people of color, that does not want to build a wall around our country and separate us from the rest of the world. This is a concert about peace.”

The concert was Madonna's latest act of support for HRC. She previously promised blowjobs for votes (jokingly of course) and proclaimed "I'm voting naked with Katy Perry!!" along with a topless photo after the "Rise" singer released her Funny or Die video.
