Some girls get all the luck. While celebrating her 31st birthday over the weekend, Paris Hilton scored $30,000 playing blackjack at the Wynn Las Vegas.

Hilton tweeted about her haul, writing" "#BirthdayGirlsLuck. I love gambling." She later tweeted that the night was "EPIC."

The socialite is now jetting around the world promoting her new line of sunglasses. Apparently, even the rich have to work.
