Selena Gomez posted a revealing photo on Instagram, and whether she noticed it or not, she gave fans a bit more than they expected from the “Come & Get It” singer.

Gomez’s breast and nipple were out in a photo of herself with some of her girlfriends, simply captioning the picture “NY.”

The 21-year-old singer was wearing a very skimpy black, lace crop top with a black high-wasted skirt in the photo. Surely, she was alerted to the nip-slip after she posted it but as of Thursday, it’s still up on her account.

She posted another group shot with the caption "’why does everyone do the kiss face? I don't get it.’ ..guilty. Unfortunately.”

Perhaps Gomez is sending a message to her on-again, off-again boyfriend, Justin Bieber, 20, who posted a series of pictures of himself getting cozy with model Yovanna Ventura on Tuesday.

Gomez and Bieber seemed to have rekindled their romance in June when they were spotted out together several times, but in true Jelena fashion, they’re back to making each other jealous.
