Sure, R&B can be smooth as silk, but the biggest singers still know how to party ... can you guess who this R&B superstar is?

We caught up with this performer while she was leaving a restaurant in Hollywood back in 2019, and it looked like she was really making the most of the moment ... because it took her a while to get to her car!

Still, she didn't mind answering one of our questions before she jetted off for the night -- and we can confirm she sounds just as sweet when she's talking as when she's singing!
