Selena Gomez flaunts 'nip-slip' in Instagram pic

Selena Gomez has posted a picture of herself on Instagram where she appears to have a nipple slip.

The 'Slow Down' singer was seen wearing a thin vest top and no bra while posing with her friends and she later uploaded the image, where the nip-slip is very evident, on her Instagram account, the Mirror reported.

The on-again, off-again girlfriend of Justin Bieber posted another snap surrounded by friends and showing off a leather black skirt to match her revealing top.
