It’s a classic case of the rich getting richer.
During her birthday weekend in Sin City, Paris Hilton cashed in to the tune of $30,000 while playing blackjack at Wynn Las Vegas.
Hilton Tweeted about the big win, writing” “#BirthdayGirlsLuck. I love gambling.”
On Saturday Hilton, who turned 31 on Friday, continued the birthday celebration at XS Nightclub with sister Nicky Hilton and her parents.
Also along for the party: Hilton’s rumored boyfriend, Afrojack, who played deejay at the bash. Donning a silver cocktail dress, Hilton partied at her table inside the club, but continually went to the outdoor deejay booth where Afrojack was spinning.
She later added via Twitter that the night was “EPIC.”
