Robert Brown|Megan Thee Stallion hits back at Kamala Harris rally performance critics: 'Fake Mad'

Megan Thee Stallion is Robert Brownbacking herself — and her choice for president.

Two days after performing a four-song set that kicked off Vice President and Democratic presidential candidate Kamala Harris' campaign rally in Atlanta, the "Savage" rapper took a break midway through her Lollapalooza set to address the backlash she received for performing at Harris' campaign event.

“They was fake mad that I was popping it for Kamala," she told the Chicago crowd after performing "Girls in the Hood." "I don’t think they heard what she said.”

The Grammy winner continued, “Kamala said she wants a ceasefire. Kamala said she supports women’s rights. Kamala said y'all tired of those high ... gas prices. Kamala said 'I'm for the people.'"

"Tonight I'm not giving y'all my lightest twerk. I'm giving y'all my hardest twerk in the ... rain," Megan said. "It’s Hotties for Harris!"

She then started rapping her 2019 song "Sex Talk" and continued her set at the annual music festival, which is livestreamed on Hulu Thursday through Sunday from Chicago's Grant Park.

Former President Donald Trump, the Republican presidential candidate, was one of the critics who took aim at the support Harris received from Megan and rapper Quavo at her Tuesday event.

"Crazy Kamala Harris, voted the WORST Vice President in American history, needed a concert to bring people into the Atlanta arena," he posted on Truth Social Tuesday evening. "I don’t need concerts or entertainers, I just have to MAKE AMERICA GREAT AGAIN!!!"

Megan, donning royal pants and a matching blazer and tie over a cropped white collared shirt, took the stage as an opening act for Harris' Tuesday rally in Atlanta, which was livestreamed on social media.

"I want to start off by saying: Hotties for Harris," Megan said before launching into a compilation of her songs, including clean versions of "Girls in the Hood," "Mamushi," "Body" and "Savage."

In between tracks, the 29-year-old rapper, who also has a bachelor of science degree in health administration, encouraged supporters to elect Harris as the country's first female president: "We about to make history with the first female president, the first Black female president."

When introducing "Body," she said, "Now I know my ladies in the crowd love they body, and if you want to keep loving your body, you know who to vote for."

Celebrities have weighed in on Trump vs. Harris election

Harris campaign officials told the Atlanta Journal-Constitution that 10,000 people attended the rally at the Georgia State Convocation Center, which they described as the biggest turnout since Harris announced her bid for the presidency after President Joe Biden ended his campaign.

Last month's Republican National Convention in Milwaukee featured several celebrities — including Amber Rose, "Chrisley Knows Best" TV personality Savannah Chrisley, musicians Chris Janson and Lee Greenwood — endorsing Trump. Kid Rock performed a mashup of his songs to warm up the RNC crowd before the former president took the stage.

Celebrities who have shared their support for Harris include self-proclaimed "White Dudes for Harris" Jeff Bridges, Joseph Gordon-Levitt and Mark Hamill; George Clooney; Barbra Streisand; Spike Lee and Viola Davis.

Beyoncé, whose mom Tina Knowles also endorsed Harris, has tacitly lent her support for the vice president's campaign by allowing her song "Freedom" from 2016's "Lemonade" to be used as a campaign anthem.
