Actor Donald Glover — aka Grammy-winning music maker Childish Gambino — has revealed his hit song “This is America” was originally an attempt to put a fellow rapper on blast.

“The idea for the song started as a joke — and it started as a Drake diss, to be honest,” Glover, 39, told GQ in a new video feature about his “most iconic” characters. “As like, a funny way of doing it. But then I was like, ‘This shit sounds kinda hard, though.’ You know? So I was like, ‘Let me play with it.’ “

After adding more elements to the song, the the 39-year-old multi-hyphenate realized it was too good to waste on hip-hop’s “Certified Lover Boy.”

So, the double Emmy-winning star and creator of FX’s “Atlanta” laid the diss track to rest and transformed the song into a cultural anthem during 2018’s “uprising and riots that were happening.”

He wanted the song to feel like a “‘We are the World,’ for like trap [music],” Glover said.

Glover worked with director Hiro Murai to develop the acclaimed “This is America” music video by studying Michael Jackson’s “Thriller” clip and the dance moves of singer Robbie Williams.

The duo “studied how that became iconic” and wanted to replicate those elements in the music video by shooting the music video on film with two takes for most of the scenes.

The “Redbone” singer also revealed that had the initial idea for “This is America” three years before releasing the single: “Time is the oven that makes something special,” he said.

The result: A track that scored four 2019 Grammys, for Best Song, Record of the Year, Best Music Video and Best Rap/Sung Performance. (Glover already had a 2018 Grammy for Best Traditional R&B Performance for “Redbone.”)

Glover’s intricate process also paid off when the song debuted at No.1 on the Billboard Hot 100 — in addition to making history as the first rap song to win the two top golden gramophones on “music’s biggest night,” according to Forbes.

Meanwhile, the rapper’s feud with Drake began in 2014 when Glover dissed the “Hotline Bling” rapper and other rising lyricists during a freestyle performance in Australia.

“Nah, I ain’t Drake. I sing better. I do better. My s–t’s wetter,” he rapped in 2014.

“I’m the best rapper, definitely top five,” he continued. “I’ll cut their heads off, that’s every rapper living. That’s Kendrick, that’s Drake, that’s ScHoolboy, that’s everyone. I don’t give a f–k.”

Glover and Drake reportedly never had a personal vendetta against each other, his diss was just an attempt to claim the rap game throne.

However, the comedian is still throwing out disses. Elsewhere in his new GQ interview, he claimed Tina Fey told him that he was only hired as a writer on “30 Rock” thanks to NBC’s diversity initiative.

“It was a diversity thing,” Glover told GQ in April’s cover story. “There is no animosity between us or anything like that, but [Tina Fey] said it herself.”

“It definitely didn’t feel like I was supposed to be there,” the “Swarm” director said.
