Paris Hilton has us seeing stars!

The beautiful blonde heiress flashed a custom tank top under a plaid shirt ... with carefully placed stars. Twinkle, twinkle!

Ms. Hilton's sexy photo was taken by celebrity photographer Terry Richardson.

Just last night, the young mogul enjoyed a girls' night out with sister Nicky and Formula One racing heiress Petra Ecclestone. Girls just want to have fun ... especially Princess P!
