Not long after Justin Bieber shocked Belibers everywhere with pics of himself and what looks like his new lady, Selena Gomez busted out (no pun intended) her own scandalous photo. 

The 21-year-old pop star posted on her Instagram late Wednesday a NSFW photo of herself and friends in NY, oh and apparently one of her nipples is exposed…

The photo shows Gomez baring cleavage in a skimpy, dark lace crop top…but is it part of the lace or an actual nip slip? 

You tell us!
