Selena Gomez didn't hold back when she stepped out in a seriously thin vest top and no bra on Wednesday, but it seems she's keen to go even further to shock us all.
The brunette beauty has posted a snap on Instagram where she appears to have a nipple slip as she poses next to friends.
Maybe she didn't notice? That or she really doesn't mind at all.
In the black and white snap, Justin Bieber's ex is pouting her heart out in a VERY low-cut black lace bandeau, and has pushed her boobs so far forward, frankly it would be a miracle if everything stayed covered.
