Rob Kardashian and Bruce Jenner aren't the only ones in the family who have undergone dramatic transformations!

In honor of Flashback Friday, here's a look at Kim Kardashian's face today (well, technically yesterday) and all the way back in 2007, with a couple of snapshots in between then. We can't believe how much the sex tape/reality TV starlet has changed over the years -- from her hair color to certain features on her face, it's like she's a whole new person!

Kim stepped out in Beverly Hills on Thursday afternoon in a sexy black outfit, but who's looking at her curvy bod when she's flashing this gorgeous smile?
