When not performing on stage in provocative outfits, Rihanna loves to chill in comfort.

The 23-year-old songstress, rockin' a striped onesie, was hard at work while recording new tracks for her upcoming album Talk That Talk.

RiRi Tweeted, "DONE B***HES!!!!"

Some of the new songs include "Where Have You Been," "Fool in Love" and "Do Ya Thing."

We're loving RiRi's low-key look with barely any eye makeup. However, she still loves that red lipstick ... and we do, too!
