Restraint. Privacy. Subtlety. These words are NOT part of Sofia Richie's vocabulary ... but then she's a young 21 years old and she's got a lot more learning to do!

Sofia has officially adopted the show-offy attitude of the Kardashian, with her proximity to the reality-show clan given her relationship with Kourtney's baby daddy Scott Disick and her newly-minted BFF status with Kylie Jenner.

Flashy cars, revealing crop tops, and publicizing a glamorous lifestyle are all part of Ms. Richie's M.O. now. When we spotted her running errands yesterday she was showing some skin in a black sports bra and yoga pants -- and these weren't just any Spandex athleisurewear pieces, they're SKIMS! Kim Kardashian's line of foundations and lingerie. In fact, Sofia posted a clip to her Instagram Story, tagging SKIMS in what was obviously a paid endorsement. Don't get it twisted, Sofia's on the KarJenner payrole, for sure!


And just the day before, we spotted Sofia lunching at the Hotel Bel-Air, rolling up to the valet in boyfriend Scott's Rolls Royce SUV!!! The $350K Cullinan is NOT your average car, even by LA standards. But Sofia's loud and proud, people! She's living the life and she wants everyone to know!
