Selena Gomez mocks Justin Bieber

Selena Gomez can't help but notice how popular her ex-boyfriend Justin Bieber is with the girls.

The 21-year-old enjoyed a little laugh at Justin's expense by posting a picture of herself in all her natural, unadorned glory on her Instagram page on Friday.

Of course the caption might throw a few people, but for those who follow every step and turn Selena and Justin make, it's a no-brainer.

'I thought he only liked the Latina category. Smh... #nomakeup #hatewhengirlssaythat,' Selena wrote.

It must refer to Justin's continuing way of flaunting his attraction to idolising young women wherever he goes.

On November 19, Justin posted a snapshot on his Instagram account of himself getting a kiss on the cheek by long-haired girl in a black leather short-cropped top and shorts ensemble.

The girl is shown with her eyes almost closed in apparent ectasy and pulling Justin closer by his chain necklace.
