The 37-year-old socialite took World War II veteran Sidney Walton to Phillipp Plein's New York Fashion Week show.
A source told the New York Post: "Paris has known Sidney for many years. He's a huge fan of Paris', and he loves to attend her DJ shows and events . . . He thinks she's the sweetest and most beautiful girl.
"She has a big heart and wanted to make his 100th birthday special."
The fashion show featured a three-course meal and a performance by Lil Pump and Sidney seemed to enjoy the entertainment.
Meanwhile, the beauty recently insisted she will be keeping her $2 million 20-karat diamond engagement ring following her split from Chris Zylka, saying: "It's mine."
