Introducing … Kardashian Week! In honor of the 10th anniversary of KUWTK, we’re celebrating big time at Life & Style. Check back each day this week for more fun features about your favorite reality TV family.

Nobody takes the term “reinventing yourself” more seriously than the Kardashians — all it takes is one look at a before-and-after pic to realize the extent of it. In just a decade, the famous family has completely transformed themselves with new faces and new bodies. And while none of them have ever owned up to any serious plastic surgery, clearly something fishy’s going on.

Kylie Jenner has changed so drastically in just two years, that making memes of her “old face” has become somewhat of a trend. While the 19-year-old has confessed to getting lip fillers, many fans have speculated that she’s had a boob job — something she still denies to this day.

“No, people – I haven’t gotten breast implants! Everyone is obsessed with that. Truth is, as I’ve gotten older, I’ve gained 15 pounds and my body has changed,” she said. “I’ve definitely filled out.” And if you’re wondering why her face looks completely different, she addressed that, too.“I swear there are things you can do to work on problem areas without having to think about plastic surgery,” she explained. “Contouring has changed my life!”

Plastic surgery or not, one thing’s for sure — the Kardashians have definitely had the ultimate glow up since stepping into the spotlight. To show you just what we mean, we Photoshopped the girls next to their old selves. Check out the pics to see just how much the Kardashians have changed over time.
