Before Kim Kardashian broke the Internet and was considered the queen of reality television, she was simply known as Paris Hilton’s sidekick. And before Hilton even considered Kardashian a friend, she used to pay her to organize her closet.

Kardashian has since done bigger and better things, like star in 10 hit seasons of “Keeping Up With the Kardashians,” produce multiple fragrance, fashion and beauty lines and become the wife of Kanye West and the mother of 19-month-old North.

To give her old best friend a shout-out on her birthday, Kardashian took to Twitter to share a picture. “Found this pic while unpacking! It's from 2006 in Ibiza. Happy belated birthday @ParisHilton.” The post quickly garnered more than 2,500 shares and over 7,500 likes from Kardashian’s 29.1 million followers after it was posted to social media for less than two hours.

Hilton shared the photo on her page, but didn’t follow up with another post to thank Kardashian for the birthday wish. She did, however, mention earlier that she went to Bodega Negara to celebrate with a different friend. “Such a fun restaurant & the food is amazing!” Hilton wrote.

Both Kardashian and Hilton, who just turned 34, were in New York for New York Fashion Week. The former BFFs did not take any photos together and were not spotted at the same shows.

The reality star, however, was pictured with someone else at NYFW: her daughter, North. The toddler did not seem happy to there and even had two tantrums, which were widely documented through photographs. Some remarked that by forcing a fussy toddler to go to fashion shows, Kardashian was treating her daughter like a shiny accessory.
