Enough has been said, written, re-written, hashed and rehashed about Selena Gomez and her private life, alleged pregnancy and her topsy-turvy liaison with Justin Bieber. But this one takes the cake.

Selena Gomez peddled back to newlines after she posted a hot racy nude picture of herself on Instagram today.

By now, the world is just plain tired of Justin's shirtless selfies. So Selena decided to give her alleged boyfriend a run for money by stripping down to her birthday suit in a naked selfie. Seems the battle for sexy-selfies has got intense with this one.

The 21-year-old singer just dropped a pic of herself on Instagram in her birthday best.

Selena uploaded a pic of her wrapped in a sheer curtain and seemingly showing everything. The beautiful picture captures her slim silhouette caught within curtains as sunlight floods her room.

Not to be left behind, Biebs too posted a shirtless bedroom eyes pic, complete with gold chain, and hoodie, not to miss the iron cross tattoo in the middle of the chest.

So which selfie you like best? Make your pic.
