Accompanied by her loved ones including her parents and boyfriend, the celebrity host took to the stage in front of fellow party-goers, the Daily Mail reported.
She writhed around on the stage floor, as she greeted fans dressed in racy suspender illusion tights and a short black frock featuring gold sequin patterns.
The socialite teamed it with high heel shoes and a head slide in the shape of cat ears. Her 21-year-old partner River Viiperi was a gentleman and swiftly lifted her up off the floor to help save face.
Apparently, the group attended the event from 12:45am until 3:30am but Paris’ fun and frolics came screeching to a halt the following day when her toy boy was admitted to hospital.
The reality TV star continued her birthday celebrations on Sunday by hitting the slopes with her man. But the fun was cut short by a scary skiing accident.
“Just got out of the hospital with @RiverViiperi. He was doing a high jump while skiing and the ski sliced in to his leg! 19 stitches! Oww! (sic)” she tweeted.
Hilton played the doting girlfriend as she sat by her boyfriend’s hospital bedside, but admitted that she “almost passed out” after seeing the nasty cut on his leg.
“Such a scary day on the slopes today. After seeing the gash on @RiverViiperi’s leg, I almost passed out. I have never seen a cut that deep in my life. He is so brave, I can’t even imagine the pain he went through today. (sic)” she wrote.
