Selena Gomez rocked a surprising new fashion trend in Paris on Saturday. The 23-year-old served up a whole new take on the pajama trend when she left her hotel in Paris in an actual pair of pajamas. She rocked her sleepwear, right on the sidewalk, even pairing the look with high heels.

Sporting straight hair and ruby red lipstick, the "Same Old Love" singer stepped out in navy blue pajamas and red high heels to promote her upcoming album, Revival, at a recording studio in the French capital.

While Rihanna has led the crusade to make pajamas acceptable as real clothes, most of the silk outfits she’s worn outside are not actually made for sleeping. Selena, on the other hand, dove in head first and opted for straight-up sleepwear.

The navy blue set that features a cropped pant is a Derek Rose London set that costs $212.

The star has been serving up major style inspiration while skipping across the pond, dominating with her street style in both London and Paris.

The pajama trend is hard to pull off, but if anyone can make it work, it’s definitely Selena.

Aside from this interesting casual-meets-glam look, Gomez's fashion game has been on point lately.

Dressed in a gorgeous white flowy wrap dress with a gold-studded belt, Gomez looked like she was reliving her royal Monte Carlo days when she stepped out Saturday evening. Gomez played the lead role of Grace, a young girl who is mistaken as a British heiress, in the 2012 film about three best friends vacationing and having the time of their lives in Paris.

Before jetting to France, Selena was promoting her second solo album, which drops October 9, in London. She took to Instagram to share a photo in another fashionable outfit, a custom Atea Oceanie slip dress, which she wore to an interview on the Alan Carr: Chatty Man talk show.

"I won't post a lot of pics like this but I have to say this was one of my favorites! Made me feel like Jennifer Aniston. LOVE YOU @ateaoceanie," the singer-actress wrote.
