Paris Hilton Shares Iconic Bikini Pic With Kim Kardashian

Paris Hilton pulled out all the stops for BFF Kim Kardashian's birthday this year. The socialite, 42, marked the SKIMS mogul turning 43 in October, posting to Instagram with a celebratory share and going image-heavy with a gallery of mostly old photos. Sharing some of the most iconic Kim and Paris moments, The Simple Life alum reminded fans of the close bond she has with the billionaire, also including a famous bikini snap. Kim started out as Paris' stylist in the 2000s. Now arguably more famous than Paris herself, Kim has conquered Hollywood and the business world, but she hasn't let her friendship with fellow reality star Paris fall apart.

Opening her gallery with the most iconic shot of all, Paris shared the time when she and Kim went full-on Louis Vuitton.

Posing backed by ocean waters and a distant beach, Paris highlighted her slender frame in a white bikini top covered in multicolor monograms shouting out LV. The mom of one added in tiny white shorts as she also brandished a metallic-effect purse from the luxury French designer. Kim, meanwhile, wore a reddish-colored beach dress as she, too, showed off a gold version of Paris' silver handbag.

Also included was car-set selfie footage of the duo, plus the 2020 parking lot shot showing Paris and Kim in 2000s-style velour tracksuits. Giving a nod to the Juicy Couture loungewear both wore two decades ago, this photo put on a modern-day twist to it all as it promoted Kim's 2019-founded SKIMS brand.

Paris also made sure to include a wedding snap, where Kim posed next to her and in a cut-out black dress. "Happy Birthday @KimKardashian! 🎈🎂👸🏻💗 So many fun memories together! Look forward to making more🥰 Sending you lots of love on your special day! Hope all your birthday wishes and dreams come true!✨ Keep Sliving!🔥Love you💘," a caption read.

The comments section has exploded, and it's largely filled with fans gushing over Kim, Paris, and the close bond the two have.

"I love how sweet you are always shouting out birthdays 😭 nice girls dont age✨," one user said. "Paris you are such a vibe.. You show everyone love and I love that about you," another replied.

While Paris and Kim are now thick as thieves, there was a time when the two appeared to have distanced themselves. Kim's fame rose after Keeping Up With The Kardashians began airing in 2007. In 2011, she stated:

"We don’t really talk. As I always say, everyone comes into your life for a reason, a season or a lifetime. And she was in my life for a long time,” adding: “There comes a point in life where you just grow apart and realize you’re not as similar as you thought. And I never run into her anywhere. Isn’t that so weird?”
