Kamala Harris has Jessica Chastain's support — and her 2-year-old daughter Guiletta's!

In a fun video posted after former Vice President Joe Biden announced California Sen. Harris as his running mate in the 2020 presidential election, Chastain showed off her child's impressive collection of dolls created in the likeness of women in politics — among them, Ruth Bader Ginsburg, Elizabeth Warren and Harris, 55.

"A lot of kids play with Marvel characters and Barbies and that's fine, but my kid ... she plays with superheroes," said Chastain, 43, holding up the Harris figure. "Hello, madam vice president."

She captioned the Tuesday video on Twitter, "Queen Veep <3 @JoeBiden choose @KamalaHarris as his running mate and me & my kid are HERE FOR IT."

Ending weeks of ever-more-fervent speculation, Biden, 74, announced Tuesday that Harris was making history by becoming his running mate.

"I have the great honor to announce that I've picked @KamalaHarris — a fearless fighter for the little guy, and one of the country's finest public servants — as my running mate," he tweeted.

Following the announcement, Harris wrote on Twitter that Biden "can unify the American people because he's spent his life fighting for us. And as president, he'll build an America that lives up to our ideals," adding, "I'm honored to join him as our party's nominee for Vice President, and do what it takes to make him our Commander-in-Chief."

Harris is the first Black woman and first Indian-American on either major party's presidential ticket. She is the fourth woman on a major presidential ticket, after Democratic vice presidential nominee Geraldine Ferraro in 1984, Republican vice presidential nominee Sarah Palin in 2008 and Democratic presidential nominee Hillary Clinton in 2016.
