Flo Milli Came to Flex

The 20-year-old rapper has star power off the charts, and she’s just warming up.

If you haven’t heard of Flo Milli, ask the nearest teen to finish the line “I like cash . . .” They’ll almost certainly respond with a singsong-y “and my hair to my ass!” — the indelible opening line from her signature hit, “Beef FloMix.” Milli, 20, recorded it two years ago out of boredom, freestyling over a minor Playboi Carti hit that now sounds weary and washed-out compared with Milli’s vibrant, convincing remake. Soon her song was blowing up on TikTok and featured in countless fancams (compilation videos that fans use to pay tribute to their favorite celebrities), and racking up more than 54 million Spotify plays. “One day I was at college, and the next day I was in New York at label meetings,” says Milli, who studied business before leaving school and signing with RCA. “I grew into it very fast. I just had to change my mindset.”

Her first full-length mixtape, the amusingly titled Ho, Why Is

You Here?, is packed with witty retorts, punchy pop-trap beats, and her own star power. She’s unstoppable, and she lets you know it while batting her lashes. Milli, who grew up in Mobile, Alabama, views her music as a way of reaching out to kids like she once was. “I like to make fun music where girls can be themselves and be free,” she says. “I never really liked high school, so I would depend on music — on the bus, going to school, in class. I just wanted to give that back.”
