Just leave me be 🥰

A post shared by Sofia Richie (@sofiarichie) on



Life is good when you're dating Scott Disick! Sofia Richie is still tooling around Italy after celebrating pal Kylie Jenner's 22nd birthday on board a $250 million yacht -- and Kylie's back in LA!

As the future Mrs. Disick enjoys the last days of summer with Scott, Kris Jenner and friends, she's posting up a storm on Instagram, showing us how much better her life is than ours ... and oh, it is!

Plus, her 20-year-old body is clearly better than ours ... but not without a little help from Mr. Plastic Surgery! Sofia seems to want desperately to fit in with the Kardashian clan so she's adopted some of their physical traits including the surgically-enhanced breasts and lips. Don't get us wrong, she looks great -- and I mean, check out that butt! -- BUT did she really need all that?

Even Kylie's reminiscing about being on the boat and not mincing words when describing how the amazing her life is (and how our lives aren't nearly that great), posting this clip of her yacht jump. Funny ... a friend off-camera says, "Go like a pencil." Well apparently it's been a while since Ky picked up a pencil because her form was more of a T-shape which means her arms SLAPPED the water like I don't know what!
