Check out this snippet of a new Lizzo song she just teased on social media … Lizzo raps, “Fat ass, pretty face with the titties / B*tch I got good genes like I’m Sydney.”

It’s unclear when the song will drop, but it looks like Lizzo already filmed a music video. She doesn’t give the track a title either … but the Sydney lyric has folks buzzing.

Lizzo’s already trolled Sydney for the controversial ad … getting political after people started claiming the commercial was a racist dog whiste

Now, Lizzo’s using all the attention Sydney’s getting to her own benefit … so she can line the pockets of her own jeans.

Sydney’s been mum on the whole AE drama … but Lizzo’s got plenty to say.
