While it’s no secret that many artists in the industry use ghostwriters for their hit songs, Lil Yachty recently dropped a bombshell when he claimed he penned the twerk-anthem “Act Up” by the City Girls.

In an interview with 23-year-old Kerwin Frost, Yachty opened up about his involvement on the track, stating, “One day I was in the studio with my best friend, Earl, and he played the beat. He was like, ‘Write something for the City Girls.’ And I was like, ‘Okay.’ And I just did it,” he recalled.

The Nuthin’ 2 Prove rapper says when the song initially came out many people were surprised to see his real name, Miles McCollum, listed in the writing credits. “[They] were like, ‘Maybe he did like how Kanye have 12 writers. He may have said one thing in the studio and they [credited] him,” Yachty told Frost. “I wrote the whole song,” he clarified. “Except for JT’s last verse. But everything that everyone is singing and all. I wrote the whole thing.”

When asked about his songwriting process and how he was about to produce such a female-driven track, Yachty explained, “I just thought like them. I know them personally. And I know what women like to hear.” According to the Georgia native, when he first heard the track he thought, “What’s just some raunchy s—t?”

Yachty’s mind-blowing admission sent some fans into a frenzy, with some calling him “genius” and others calling out the need for more female rappers who write their own material.

In addition to being a songsmith for others, Yachty released his third studio album, Nuthin’ 2 Prove, in October 2018. The LP was met with mixed reviews, receiving a 52 out of 100 on Metacritic. This Summer, fans can catch him at this year’s Lyrical Lemonade Summer Smash Festival in Chicago on the weekend of June 29 through June 30.
