Ahoy, Mateys! Paris at Treasure Island

TMZ spotted Hilton walking into TI last night, where she met with 35 of her closest friends for dinner at Social House. Sporting a super cute bob -- see ya later extensions! -- Paris clomped her giant feet across the casino floor, talking on her cell the whole time.

Hilton is in town to celebrate the launch of her Dollhouse clothing line, with parties at Social House and PURE Nightclub at Caesars Palace.
