Sofia Richie Calls Kylie Jenner Her 'Best Friend' in New Footage From Makeup Mogul's Birthday

These two BFFs are adorable!

Kylie Jenner posted a video compilation this week on Instagram from her 22nd birthday party. The Kylie Cosmetics founder kept things simple this year for her big day…she rented a $250 million mega-yacht and invited her closest family and friends to party along the most beautiful coasts of Italy.

Kylie starts the clip off by saying, “It gets better with age, people!” Then the video launches into a montage of dancing, banana rides, drinks, presents, fashion poses, and laughs.

Of course, no Kardashian video would be complete without individual interviews from the partygoers. We hear from Kylie’s mom, Kris Jenner, her friends, and, last but not least, we hear from Scott Disick’s girlfriend, Sofia Richie.

Richie first jokes, “Kylie, you’re 22 and you’ve always been one year cooler than me so…” Richie recently celebrated her 21st birthday in Las Vegas with Kylie and her closest girlfriends.

Richie then continues, this time in ski goggles, “But I love you! You’re my best friend. I don’t know what life would be like without you.” How precious!

The two ladies have become very close over the last year, especially after Kylie’s friendship with her longtime BFF, Jordyn Woods, dissolved after she was involved in an alleged kiss with Kylie’s sister, Khloé Kardashian’s, then-partner and baby daddy, Tristan Thompson.

It looks like Kylie was truly surrounded by love on her big day!
