A representative for Selena Gomez has dismissed speculation the singer has been caught up in a racy photo scandal, insisting new pictures showing the star purportedly locking lips with another girl are "fake".

A steamy snap of a teenager thought to be Justin Bieber's girlfriend smooching a female pal went viral on Monday, with many gossip bloggers teasing the kiss as one of the "Who Says" hitmaker's wildest moments ever caught on camera.

But the 19 year old star's spokesperson has spoken out to shoot down the claims, telling GossipCop.com, "The photo is a fake."
