Kendall Jenner And Hailey Bieber: A Decade Of Socal Sisterhood And Hollywood Highlights on ONDA LA

The SoCal Bond That Started It All

Picture this: it’s 2012, and two young stars are about to become inseparable in the heart of Hollywood. Kendall Jenner and Hailey Bieber (then Baldwin) first crossed paths thanks to Kendall’s sister Kylie, kicking off a friendship that’s pure LA magic. From that initial meet-cute at The Hunger Games premiere, these two have been glued at the hip, navigating fame, fashion, and all the drama that comes with it.

Hailey later spilled the tea on her YouTube series Who’s in My Bathroom?, reminiscing about those early days. Kendall couldn’t resist a playful jab, saying Kylie might’ve introduced them, but she was the ‘more fun’ sister. Hailey laughed it off, admitting their bond deepened when Kendall started modeling and popping into New York, where Hailey lived at the time.

That same year, they strutted their stuff together on the runway for Sherri Hill at New York Fashion Week. Designer Sherri Hill couldn’t stop raving to W Magazine about their beauty, brains, and hustle - a combo that’s basically their trademark now.

Red Carpet Rulers and Milestone Memories

2014-2016: Birthdays and Ink

Fast forward to November 2014, and Hailey’s 18th birthday bash in LA was a full-on Jenner affair with both Kendall and Kylie in the mix. The trio snapped pics that screamed early-2010s vibes - think skinny jeans and selfie overload. By May 2015, they were owning the Met Gala red carpet with pals Gigi and Bella Hadid, Kendall rocking a green Calvin Klein stunner and Hailey debuting in a cute blue Topshop mini.

Their friendship got permanent in August 2015 with matching tiny broken heart tattoos on their fingers - a SoCal rite of passage, if you ask us. Hailey flaunted the ink on Snapchat, proving their bond was deeper than just Hollywood hype. Then, in November 2016, Hailey joined Kendall’s 21st birthday rager, starting at Catch and ending at Delilah, a West Hollywood nightlife gem, with A-listers like Kim Kardashian and Cara Delevingne in tow.

2017-2019: From Courtside to Coachella

By 2017, these two were everywhere together. They kicked off the year courtside at a Lakers vs. Grizzlies game at the Staples Center (now Crypto.com Arena, for you non-LA folks), rocking casual fits like true Cali girls. That April, they brought their bold festival energy to Coachella in Indio, slaying looks for a Bumble activation with that desert heat vibe.

In 2018, they owned New York Fashion Week, walking for Daniëlle Cathari’s Adidas Originals show, and later that year, belted out Miley Cyrus’s ‘Party in the U.S.A.’ on Carpool Karaoke with Miley herself crashing the party. Come 2019, they were back at Coachella, repped Justin Bieber’s Drew House brand, and stunned at the Met Gala - Hailey in pastel-pink Alexander Wang, Kendall in dramatic orange Versace feathers.

That summer, they jetted to Jamaica for Justine Skye’s birthday, living it up with cliff jumps and tropical vibes. And when Hailey tied the knot with Justin Bieber in September 2019, Kendall was right there, planning the bachelorette bash at Ysabel and Delilah, and shining at the South Carolina wedding in a sleek black-and-gold gown.

2021-2023: Supporting Each Other Through Life’s Big Moments

By 2021, their friendship was all about being real. Hailey had Kendall on Who’s in My Bathroom?, where they got deep about supporting each other in an industry that can chew you up and spit you out. They hit the Met Gala again that May, Kendall in a sheer jeweled Givenchy and Hailey in sleek black Saint Laurent, proving they can do glam like no one else.

In 2022, they cheered on their teams at Super Bowl Sunday in LA with their then-partners, Devin Booker and Justin Bieber, soaking up that SoCal sports energy. By December 2023, they were back on the red carpet at the Academy Museum Gala in Los Angeles, Kendall in a red Fendi turtleneck gown and Hailey sparkling in a Saint Laurent halter dress - pure Hollywood royalty.

“We’ve seen each other shine at different times, and no matter what, we’ve never let this crazy industry mess with our bond - that’s rare in LA,” Kendall shared during a candid chat on Hailey’s YouTube series.

2025: Still Slaying Together

From Santa Monica Nights to Coachella Collabs

2025 has been a banner year for this dynamic duo. They kicked things off with a chic girls’ night at Giorgio Baldi in Santa Monica - a fave spot for celeb sightings - rocking coordinated black fits with friends like Devon Lee Carlson. Then in April, their brands, Kendall’s 818 Tequila and Hailey’s Rhode, teamed up for a Coachella photo booth that had everyone buzzing with that desert festival energy.

Hailey captioned a post, ‘bestied so hard our brands collabed at Coachella,’ and we’re obsessed with this power move. By May, they were back at the Met Gala, nailing the ‘Tailored for You’ dress code - Hailey in a Saint Laurent blazer mini, Kendall in a gray Torishéju skirt suit. On the carpet, Kendall called them ‘sisters,’ while Hailey described their dynamic as ‘golden retriever and black cat’ - spot on!

Fall Glam and Beyond

In a May 2025 Vogue profile, Hailey opened up about motherhood and mental health, with Kendall praising her ‘motherly’ and ‘goofy’ side, saying watching Hailey become a mom has been ‘beautiful.’ Their bond just keeps getting stronger, and we’re here for it.

Come October 2025, they reunited at the Academy Museum Gala in LA, Kendall in a fitted black gown by The Row and Hailey in a brown Schiaparelli couture corset dress - talk about contrasting slayage. The night before, they celebrated at the King Kylie pop-up for Kylie Cosmetics in LA, Kendall in vintage blue suede Calvin Klein and Hailey in long black Saint Laurent, reminding us why they’re the ultimate SoCal sisterhood.

From Hollywood red carpets to Malibu-style getaways, Kendall and Hailey’s friendship is the kind of ride-or-die energy we all crave. Here’s to another decade of iconic moments!
