Kamala Harris concert rallies:Lady Gaga, Katy Perry, Ricky Martin, more perform

Last week, several of Rudd's "Avengers" co-stars lent their support for Vice President Kamala Harris' presidential campaign in a video Robert Downey Jr. – aka Iron Man – posted on social media.

Downey, Don Cheadle, Scarlett Johansson, Mark Ruffalo, Paul Bettany, Danai Gurira and Chris Evans appeared in the Zoom-style video chat clip and had a lively debate about a catchphrase for the Harris-Walz campaign.

The Avengers, including Rudd, also assembled for a virtual fundraiser benefitting Joe Biden and Harris' campaign in 2020.

On Election Day eve, Lady Gaga, Katy Perry, Christina Aguilera, James Taylor, Jon Bon Jovi and Ricky Martin were among the celebrities that lent their star power to Harris Monday night.

The musicians roused crowds across the country with performances and shared why they were casting their vote for Harris. "Kamala Harris is for us. She's for unity, she's for all Americans," Martin told a Philadelphia audience while Aguilera encouraged fans in Las Vegas to "vote for freedom."

In Philadelphia, Lady Gaga introduced Harris' husband, Doug Emhoff, and performed "God Bless America."

"For more of this country's life, women didn't have a voice. Yet we raised children, we held our families together, we supported men as they made the decisions. But tomorrow, women will be part of making this decision," Gaga said. She added that she believed Harris would be a president "for all Americans."
