This is what Selena Gomez's worst nightmare looks like!

Justin Bieber posted a photo of a random beautiful girl he found online to his Instagram account yesterday, and pleaded with fans to identify her and help him track her down. "OMG who is this!" he wrote as the caption.

Who knows how The Beliebers are so good at stalking, but they turned up an answer within the hour!

The brunette beauty in JB's pic is a girl named Cindy Kimberly, who runs an Instagram account with the handle "wolfiecindyreal" and has 250K followers. The young stunner was undoubtedly flattered, but also overwhelmed with the attention. "I so do not know how to deal with this but I only have Instagram and Tumblr so whatever other stuff people are finding is fake (I did use to have a Twitter account but I deactivated)," she wrote.

We wonder if The Biebs is trying to get back at Selena for hooking up with Niall Horan by making her jealous?
