While grabbing dinner with a friend at Mexican restaurant El Cholo, Gomez donned navy blue pajamas, which she topped with a long black duster to combat the California cold. These were no ordinary PJs, however -- the silk set featured white piping, plus the singer upped the chic appeal by pairing the cozy two-piece with black pumps and red lips.
After the meal, the duo went shopping along Santa Monica's Third Street Promenade before heading into a recording studio.
Then Gomez turned heads in equally eye-catching, if not slightly more traditional, attire on Saturday during a night out at Catch LA in West Hollywood.
The 24-year-old pop star rocked an all-black ensemble that included a low-cut crop top, straight-leg pants, strappy sandals, and a thick choker. Her dewy makeup perfectly complemented the dark duds and gave her an all-over glow, thanks to a bronzed smoky eye, sunny tan, and nude but shimmery lips.
A source tells ET that Gomez was in good spirits throughout the night, laughing as she had dinner with a few friends at the celebrity hot spot for the first time. The group ordered a few different dishes, including truffle sashimi, waygu on a rock, black cod lettuce wraps, The Catch sushi roll, and the decadent HitMe dessert.
More recently, she opened up about what those 90 days of solitude were like. "During that time I did not have my cellphone," Gomez explained while participating in Thrive Global's questionnaire last week. "It was the most refreshing, calming, rejuvenating feeling. Now I rarely pick up my phone, and only limited people have access to me."
