Over the past few years, we've seen some celebrities go through some pretty sensational changes - and not just to their personal lives! Check out this mini-retrospective of stars then and now (or, in some cases, Then and Still Kinda Then) - who do you think's changed the most?

Some folks have made some crazy changes...

Others? Not so much!

Stavros hasn't changed much more than his haircut...

...but then again, a haircut did wonders for Kevin Federline!

Kate Bosworth somehow managed to get even skinnier...

Nicole, on the other hand, is still tiny - but at least now we're not worried that she'll blow away in a stiff breeze!

But the biggest change has to be Lindsay Lohan - and we like what we've seen so far!
Who's changed for the best - and who needs to change back?
