Paris Hilton celebrated her 37th birthday with a balloon-filled New York City bash that was attended by, among others, her sister Nicky Hilton, model Andrea Pejic, Real Housewives star Kyle Richards (who is also Hilton's aunt), Richards' daughter Sophia Kylie Umansky, Theodora Richards, and Alice + Olivia designer Stacey Bendet. Michael Jackson's daughter Paris Jackson was there at well.

Naturally, Paris Hilton and Paris Jackson seized the moment and took a photo together, posing with a throw pillow that said Paris though they were, actually, in New York.

"Paris & Paris ✨👯‍♀️✨," Hilton captioned the picture. (If you want to recreate the pic at home, the Paris Jet Set pillow, by Jonathan Adler, can be yours for $98 from Bloomingdale's.)

According to E! News, the younger Paris, 19, was actually named after the elder. "So I grew up knowing Michael [Jackson] very well and when he had his daughter, he always loved the name Paris and grew up being an uncle to me," said Hilton in 2009. "So he asked my mom if it was okay, and of course she said 'yes' and I think she's such a beautiful little girl and I'm proud we have the same name."
