The singer told Zane Lowe she mentioned Drizzy on her new song, "Rumors," because she felt it'd be fun to give society a taste of its own medicine -- and in this context, that means flipping the script on rappers/male musicians name-dropping fine women in their tunes.

If you didn't hear the bar yet, it goes ... "Last year, I thought I would losе it // Readin' s*** on the internet // My smoothie cleanse and my diet // No, I ain't f*** Drake yet (Ha)."

The Drake thing seems to have come out of left field ... but Lizzo explained further in the ZL sit-down, jokingly saying she hasn't quite been able to manifest some bedroom boom with Toronto's Certified Lover Boy -- even though it sounds like she'd love to take a dip.

All kidding aside, Lizzo says she included the line as a way to turn what rappers have often done in music -- namely, name-dropping ladies/would-be sexual exploits -- upside down on its head. It's true ... fellas have done that for a long time in the genre ... see Biggie's "Dreams."

As far as their real-life relationship ... Lizzo says she kinda knows Drake, and that he's super cool.

Still, it seems she does, in fact, want some of what he's got -- at least based on her Twitter activity shortly after this interview aired. She tweeted right at Champagne Papi for the whole world to see, writing ... "Hey big head @Drake." Classic "wyd" vibes for modern dating.
