This has been hitting our inbox a bit the past day or so and we didn't want to post it at first because even the tabloids weren't sure what it is. Now that a day has gone by more and more are saying it is a Vinyl Scratch tattoo (especially our source People Magazine) so I think we're safe enough to post it here and say Selena Gomez has a pony tattoo!
Whether it is permanent or not is to be seen, but it's an interesting addition nonetheless! Thanks to all of you for sending this one in.
