Paris Hilton blonde sunglasses airport nipples boobs see through no bra How does she keep her time zones straight with all this traveling?!

Paris Hilton touched down at the Ataturk airport in Istanbul yesterday, and the heiress seems to have finally figured out her travel style! Thank goodness she's decided to ditch the tracksuits and matching trainers! Although, it looks like she decided to ditch her bra as well...

The 31-year-old socialite has been attached at the hip with her hot boyfriend River Viiperi as of late, but the Spanish model didn't make the trip to the Middle East with his lady love this time around.

The blonde beauty is currently overseas on business. "In Istanbul, on set shooting the @DefactoDechino commercial with Arda Turan. Such a nice guy!" she tweeted.

We're so jealous of Princess P! She gets to travel the world and get paid doing it!

Loves it!
