Sexy and single, Paris Hilton headed off to Sin City to party the weekend away at the Hard Rock Hotel Casino in Las Vegas on Sunday (April 25).
Clad in a blindingly bright pink bikini, the hotel heiress was joined by her sister Nicky to host Rehab - which dubbed itself as The Ultimate Daytime Pool Party.
Keeping her fans and followers up-to-date the whole way through, Miss Hilton tweeted just prior to the event, "Walking thru the casino right now to my pool party! See you all in a few xoxo Paris ;)"
Having a marvelous time, the 29-year-old later wrote, "Today was so much fun! Do you like my hot pink bikini? ;)"
The Vegas trip comes just after Paris kicked off the weekend dining out with ex-fiance Jason Shaw, which comes shortly after she announced her split from Doug Reinhardt.
